Zinc(II) di(o-hydroxybenzoate) complexes with imidazole and its derivativesSynthesis, thermal characterization and molecular structures

Mixed complexes of the type: Zn(Hsal)2(Him)2, Zn(Hsal)2(Him)5, Zn(Hsal)2(4-MeHim)2 and Zn(Hsal)2(1,2-diMeim)2 (where Hsal=OHC6H4COO-, Him=imidazole, 4-MeHim=4-methylimidazole, 1,2-diMeim=1,2-dimethylimidazole) have been synthesized. The application of chemical, thermal and X-ray methods has enabled us to analyze the complexes and their sinters. The gaseous products of pyrolysis of Zn(Hsal)2(Him)2 and Zn(Hsal)2(4-MeHim)2 have been investigated. Thermal decomposition pathways have been postulated for synthesized complexes. The molecular structures of the Zn(Hsal)2(Him)2 and Zn(Hsal)2(1,2-diMeim)2 have been solved.
