Abstract

New zinc and cadmium mono- and binuclear complexes containing dioxime ligands were synthesized. Due to Zn and Cd affinity for oxygen and nitrogen atoms a high diversity of complexes containing dioxime ligands with varied composition and interesting architecture can be prepared. The use of bridging ligands offers good perspectives for assembly of bi- and polynuclear compounds, study of various components impact on synthesis and opens new directions for oriented and programmed synthesis of compounds with predictable properties. In such a way the use of some chelate ligands which coordinate with metal perpendicularly to the axis connecting metal atoms make lighter the crystalline structure and create cavities which can be embedded with small molecules. Keywords: zinc, cadmium, oxime, coordination compounds, mononuclear, binuclear.
