POLYNUCLEAR CADMIUM COMPOUNDS CONTAINING CIS-[CO(EN)(2)(OH)(2)](+) LIGANDS

摘要

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 [Cd-2(mu-Cl-4)Cl-4{(OH)(2)Co(en)(2)}(2)]ClO4 (1) and the polymeric compound [[Cd(mu-Cl)(H2O)(2){(OH)(2)Co(en)(2)}]Cl-2](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. [References: 13]
