Two new pH-controlled coordination polymers constructed from an asymmetrical tricarboxylate ligand and Zn-based rod-shaped SBUs
Graphical abstract
Two new coordination polymers based on two different rod-shaped SBUs have been synthesized by controlling the amount of NaOH added. Particularly, an unusual rod-shaped Zn-chain is formed by the independent Zn5(COO)6 clusters connected by OH− groups. This work presents that NaOH not only regulates the pH but also can participate in coordination.

Novel metal-organic and supramolecular 3D frameworks constructed from flexible biphenyl-2,5,3′-tricarboxylate blocks: Synthesis, structural features and properties
2017, Journal of Molecular StructureCitation Excerpt :The six-coordinate Zn2 atom is surrounded by five carboxylate O atoms from three independent μ4-L3– blocks and one N atom from a μ-4,4′-bpy ligand, thus forming a distorted octahedral {ZnNO5} geometry. The ZnO [2.003(4)–2.570(4) Å] and ZnN [2.090(4)–2.092(6) Å] bond distances are in good agreement with those observed in some related Zn(II) compounds [18,20,22,23,28]. In 3, the L3− block acts as a μ4-spacer (Scheme 2, mode V), in which the three carboxylate groups show the terminal bidentate and μ-bridging tridentate modes.

2016, Journal of Solid State ChemistryCitation Excerpt :It is because the CPs offer a degree of structure predictability, in addition to well-defined environments for luminophores in crystalline form. As everyone known, CPs display a wide range of luminescent behavior resulting from the multifaceted nature of their structure, and these structures are readily tunable through variation of the different ligands [18], metal ions [19], solvent [20], reaction temperature [21], pH [22] and so on [23–25]. Among these factors, the organic ligands, typically those with π-conjugated backbones influence profoundly the specific structures and luminescent properties of CPs.

2016, PolyhedronCitation Excerpt :The Zn2–O distances fall in the range of 1.891(3)–1.929(3) Å, while the Zn2–N distances lengths vary from 2.035(4) to 2.048(4) Å, and the coordination angles around the Zn2 are in the range of 97.84(14)–130.10(15)° (Table 5). The Zn–N and Zn–O bond lengths and coordination angles around the Zn(II) are in the normal range [16–17]. The Zn(1)⋯Zn(2) distance is 3.1546(9) Å.
Design and synthesis of two luminescent Zn(II)-based coordination polymers with different structures regulated by different solvent system
2016, Journal of Molecular StructureCitation Excerpt :So, tremendous efforts have been put into the elaboration of useful CPs by choosing the center metal ions or cluster nodes link with functionally valuable organic linkers [6–9]. A great number of CPs have also been proven that various key factors governing the diversity of CPs, such as metal-ligand ratio, pH, solvents, temperature, and so forth [10–15]. In particular, the nature of the solvent is an important factor among these factors because its chemical properties as well as structure can affect the rate of crystal growth and the final structures [16–20].
