Polyether Adducts of d‐Block Metal Compounds as Starting Materials for New Cluster Compounds

Abstract New crystalline cobalt, nickel, zinc, and mercury halide adducts with polyethers as ligands have been isolated, characterized, and identified as [Co(μ‐Cl) 2 CoCl 2 (glyme) 2 ] (glyme = 1,2‐dimethoxyethane), cis ‐[CoI 2 (H 2 O) 2 (glyme) 2 ] 2+ [CoI 4 ] 2– , [NiI 2 (glyme) 2 ], [ZnI 2 (glyme)], [HgCl 2 (glyme)], [CoI 2 (diglyme)] (diglyme = bis(2‐methoxyethyl)ether), [ZnI 2 (diglyme)], [HgI 2 (diglyme)], [CoCl(μ‐Cl)(diglyme)] 2 , [NiI(μ‐I)(diglyme)] 2 , [Co(μ‐Cl)(triglyme)] 2 2+ [CoCl 2 (μ‐Cl)] 2 2– , and cis ‐[(NiI 2 )(triglyme)] n . These compounds were obtained from the metal halide salts in solution of glyme or diglyme, and some of them show unusual coordination numbers and arrangements.
