Triaquatetrakis(dimethylacetamide-κO)gadolinium(III) hexacyanoferrate(III) dihydrate

Abstract

The title compound, [Gd(C4H9NO)4(H2O)3][Fe(CN)6]·2H2O, is a bimetallic complex containing two isolated metal complexes. The Fe atom is bonded to six cyano ligands forming an almost ideal octahedron. One of the cyano groups is also connected through a hydrogen bond to a water molecule bonded to the Ga atom. Aside from three water molecules, gadolinium is also coordinated by four dimethylacetamide molecules, two of which show various degrees of structural disorder. The asymmetric unit also includes two solvent water molecules, which take part in hydrogen bonding, forming an extended network.
