X-Ray crystal structure of two new mixed-valence copper cyanide complexes: unusual bi-co-ordinated copper(I) atoms in polymeric networks
Abstract
The two mixed-valence compounds [Cu4I(CN)6CuII(NH3)2]n and [Cu3I(CN)5CuII(NH3)2(OH2)]n display polymeric networks in the solid state and show co-ordination numbers three and two for the copper(I) atoms and four or five for the copper(II) atoms.
