其他摘要：The strategy of evolving synthesis of mono-, bi- and polynuclear compounds with dioxime ligands based on bridging bipyridines has been developed. Oriented synthesis of 11 copper, zinc and cadmium binuclear complexes and 9 zinc and cadmium coordination polymers has been performed. Their composition and structure were determined by modern investi- gation methods: IR spectroscopy, X-ray analysis. It was established that zinc and cadmium, are able to form coordination polymers with coordination number 6 and anions nature of the initial salt has a decisive contribution on building up their molecular architecture. The type of bridging ligand influences the specificity of polymeric chain. The ability of sulfate anions to coordinate by the oxygen atoms to the cation of central atom allows the binding of the polymeric chains with each other
