Abstract
A new coordination compound [Zn(CHZ)3][C(NO2)3]2 · (H2O)2 was synthesized and characterized by elemental analysis, FTIR and UV spectra, and its crystal structure was determined by X-ray single crystal diffraction. The crystal belongs to the triclinic system, space group \( P\overline{1} \). In the asymmetric unit, zinc (II) ion is six-coordinated with three carbonyl oxygen atoms and three terminal nitrogen atoms to form distorted octahedral structure, three CHZ molecules and central metal cation constitute three planar chelate rings which are vertical one to another, and two trinitromethanides are similar to the conformation of C 2v -like. Zinc (II) ions, carbohydrazide ligand molecules, trinitromethanide anions, and lattice water molecules are jointed to a complicated three-dimensional network structure through coordination bonds, electrostatic forces, and extensive hydrogen bonds. The thermal decomposition character and mechanism were tested through DSC, TG–DTG, and FTIR spectra. The results show that the title complex has high energy and good thermal stability.
