Abstract

The reaction between copper powder and Ba(TFA)₂ (TFA = CF₃CO₂) in methanol under air and in the presence of an aminoalcohol, afforded Cu(II) alkoxides and subsequent formation of heterometallic species or cocrystallization depending on the functional alcohol, dimethylaminoethanol (dmeaH) or N-dimethylaminoethanol (mdeaH₂), respectively. A 1D-coordination polymer [Ba₃Cu₂(μ,η²-TFA)₆(μ,η²-OC₂H₄NMe₂)₄(MeOH)₂,2MeOH]_∞, based on zig–zag chains was obtained with dmeaH, whereas mdeaH₂ lead to [Ba(η¹-TFA)₂{MeN(C₂H₄OH)₂}₂] 2a and [Cu{MeN(C₂H₄O)(C₂H₄OH)}₂] (2b) which cocrystallize as two independent molecules in the asymmetric unit cell.

Inorganic stereochemistry: Geometric isomerism in bis-tridentate ligand complexes
2021, Coordination Chemistry Reviews
In this review, we analyze the stereochemistry of hexacoordinated metal complexes with flexible tridentate ligands. Unlike rigid ligands, which can adopt only specific coordination modes, flexible ligands open more possibilities to fine-tuning the system for a specific application. Bis-tridentate [M(A-B-A)₂] complexes of flexible ligands can form three geometric isomers: mer, trans-fac, and cis-fac. The analysis of crystallographic data for 844 structures found in the Cambridge Structural Database (CSD) elucidates influences on the formation of different isomers, such as steric and electronic properties of the ligand and metal ion, type and substitution of donor atoms, and the possibility of non-covalent interactions.
Crack free and spherical shape copper-zinc composite oxide thin films fabrications by AACVD

In the FT-IR spectrum, the presence of three very strong absorption bands for C–F and C–O in the range 1120–1210 cm−1 corresponds to the TFA ligands [26]. The absorption bands due to the μ-dmap (νC−H) are prominent in the range 2800–3000 cm−1, while the absorption band close to 530 cm−1 for Cu–O is in accordance with the literature [43,44] and the absorption bands in the frequency range 428–485 cm–1 are due to νCu–N vibrations [45]. The presence of absorption bands at 1066 and 895 cm−1 is attributed due to stretching modes from ν(C–O–C) of THF molecules [46].
Crack free, mesoporous and crystalline 3CuO–ZnO composite oxide thin films have been prepared by aerosol assisted chemical vapor deposition (AACVD) using the tetranuclear heterobimetallic complex [Zn(TFA)₃(μ-O)Cu₃(dmap)₃Cl]·THF (1) (where dmap = N,N-dimethylamino-1-propanolato, TFA = trifluoroacetate and THF = tetrahydrofuran). The designed precursor 1 has been synthesized by a simple chemical reaction in high yield and characterized by its melting point, elemental analysis, FT-IR, mass spectrometry, single crystal X-ray analysis and thermal analysis (TGA/DTA). The single crystal X-ray analysis of complex 1 shows that it crystallizes in the triclinic space group $P \bar{1}$ with cell dimensions a = 10.617, b = 10.952, c = 18.713 Ǻ. The TGA/DTA analysis proved that the thermal decomposition of precursor 1 at 723 K gives the 3CuO–ZnO composite oxide residue. Crystalline thin films of 3CuO–ZnO composite have been fabricated by using AACVD on a glass substrate at 723 K in a single step without pre or post annealing. The material properties of the deposited thin films have been characterized by X-ray diffraction (XRD), energy dispersive X-ray analysis (EDX) and Rutherford back scattering (RBS) analysis, and the results proved that the deposited thin films are of the crystalline 3CuO–ZnO composite oxide, free from other impurities. Further exploration of the XRD data of the films proved the formation of the crystalline 3CuO–ZnO composite with an average crystallite size of 45 nm, calculated from broadening by the Debye–Scherrer formula. Scanning electron microscopy (SEM) showed that the spherical-like particles have a diameter in the range of 0.2–0.5 μm, sintered together to form a compact 3CuO–ZnO composite oxide thin film, and qualify the scotch tape test.
Structures and luminescent properties of Tb(III) and Tb(III)-Ni(II) coordination polymers based on pyridyl dicarboxylate

Heterometallic assemblies are interesting because the properties of one metal ion may be controlled by tuning the physicochemical properties of the other ion [9,10]. Hard–soft acid–base (HSAB) distinctions can be employed to construct heterometallic assemblies [11–13]. In this regard, pyridyl carboxylic acids are extensively explored to build heterometallic coordination polymers [14–21], because the lanthanide and transition metal ions have different affinities for the N- and O-donors [1,2,22].
The N,O ligand, namely 5-(pyridin-4-yl)isophthalic acid (LH₂), with carboxylic acid groups and pyridyl group separated, prefers to act as a bridging ligand. Its Tb(III) coordination polymer, [TbL(LH)(H₂O)₂]_∞·xH₂O (1), and heterometallic Tb(III)–Ni(II) coordination polymer, [TbNiL₂(LH)(H₂O)]_∞·xH₂O (2), have been successfully prepared. Complex 1 exhibits a two-dimensional layered structure with (4,4) network leaving all the pyridyl N-donors uncoordinated, while complex 2 has a three-dimensional structure due to coordination of Ni(II) to part of pyridyl N-donors. Both the complexes were characterized by single-crystal X-ray diffraction, X-ray powder diffraction, FT-IR spectroscopy and thermogravimetry analysis. The ligand is capable of sensitizing the Tb(III) ion, and both the complexes emit characteristic visible green luminescence of Tb(III).
Syntheses, crystal structures and properties of two thiocyanato bridged coordination polymers
2009, Journal of Molecular Structure
Two thiocyanato bridged coordination polymers {[Cd(μ-SCN)₂(htm)(H₂O)]·H₂O}_n (1) and [Cu(μ-SCN)₂(Him)₂]_n (2) (htm = hexamethylenetetramine, Him = imidazole) have been synthesized and characterized by single-crystal X-ray analyses. For these two compounds, the adjacent metal centers are bridged by a pair of μ_1,3-SCN⁻ to form 1-D array, which are further linked to 2-D supramolecular network by hydrogen bonds. And, the interactions between metal center and sulfur atom of thiocyanato ligand obey the HSAB rule. Compound 1 exhibits good fluorescent emissions. Compound 2 exhibits intra-chain Cu(II)–Cu(II) ferromagnetic coupling with J = 1.58 cm⁻¹.
Low temperature and single-source synthesis of a CuO-Ba<inf>2</inf>Cu<inf>3</inf>O<inf>5+x</inf> composite: Fabrication of thin films and characterization
2009, Polyhedron
A new heterobimetallic, single-source precursor with the formula Ba₂(μ-OAc)₄(OAc)₂Cu₄(μ-dmae)₄(OH)₂ (1) [dmae = N,N-dimethylaminoethanolate and OAc = acetate] has been synthesized by the interaction of Cu(OAc)₂ · H₂O with Ba(dmae)₂ in toluene for the low temperature deposition of CuO–Ba₂Cu₃O₅₊_x composite thin films. Complex (1) was characterized by melting point, elemental analysis, FT-IR spectroscopy, mass spectrometry, thermal analysis (TGA) and single crystal X-ray diffraction. Complex (1) crystallizes in the triclinic space group $P \bar{1}$ . A TGA study demonstrated that the complex undergoes controlled thermal decomposition at 400 °C to give the CuO–Ba₂Cu₃O₅₊_x composite. The chemical composition and surface morphology of the deposited mixed oxide thin films were analyzed by scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX) and X-ray powder diffraction (XRPD), which support the formation of the pure crystalline CuO–Ba₂Cu₃O₅₊_x composite with particle sizes ranging from 0.08 to 0.4 μm. The thickness and voltage–current characteristics of the thin films were determined with a profilometer and a voltmeter using the four-probe method, respectively.
Synthesis, crystal structure and luminescent properties of one coordination polymer of cadmium(II) with mixed thiocyanate and hexamethylenetetramine ligands
2009, Spectrochimica Acta - Part A: Molecular and Biomolecular Spectroscopy
A novel Cd(II) coordination polymer [Cd(SCN)₂(hmt)_1/2(H₂O)]₂·H₂O (hmt = hexamethylenetetramine) has been synthesized and characterized by IR, elemental analysis, TG technique and X-ray crystallography. Cd(II) atom has an distorted octahedral environment with an N₃S₂O donor set. Every six Cd(II) centers are linked by hmt and thiocyanato bridges to form a planar 2D coordination polymer containing hexagonal metallocyclic rings [Cd₆(SCN)₈(hmt)₂]. A 2D layer structure is held together with its neighboring ones via a set of hydrogen-bonding interactions to form a 3D supramolecular structure. The luminescent properties of the title complex in the solid state were investigated.
