Abstract
Polynuclear heterometallic compounds containing cobalt and cadmium were prepared by the reaction of CdCl2 with salts of the cis-[Co(en)2(H2O)2]3+ cation. X-Ray analyses of the tetranuclear Co2Cd2 complex [Cd2(mi-Cl)Cl4{(OH)2Co(en)2}2]ClO4 (1) and the polymeric compound [[Cd(mi-Cl)-(H2O)2{(OH)2Co(en)2}]Cl2]n (2) confirm that the [Co(en)2(OH)2]+ groups act as chelating ligands toward the Cd atoms. The Cd coordination octahedra are connected by a face in 1 and by corners in 2.
