Abstract (EN): Synthesis and physical properties of chromium(II) and copper(II) complexes of general formula [M(L-L')Cl2] are reported, where L-L' is one of the bidentate alpha,alpha'-diimine ligands: 2,2'-pyridylbenzimidazole; 2,2'-pyridylimidazole; 2,2'-pyridylimidazoline. The chromium(II) complexes are high spin and spectroscopic data suggest a polymeric hexacoordinate distorted chloride bridged structure; the IR active bands in the region 350-250 cm-1 have been assigned to Cr-N and Cr-Cl stretching vibrations. the spectroscopic, EPR and magnetic data for the copper(II) compounds suggest that they are structurally similar to the chromium(II) compounds.
