Tetraaquatetrakis(dimethylacetamide-O)neodymium(III) hexacyanoferrate(III) trihydrate

J. Overgaard, H. Svendsen, M. A. Chevalier and B. B. Iversen

Abstract: The crystal structure of the title compound, [Nd(C₄H₉NO)₄(H₂O)₄][Fe(CN)₆]·3H₂O, contains two isolated mononuclear ions connected through hydrogen bonding between a water molecule bonded to neodymium(III) and a cyano group bonded to iron(III). The coordination of the six cyano groups around iron(III) is close to ideal octahedral, while the eight ligands around neodymium(III) comprise a slightly distorted square antiprism. Three solvent water molecules are included in the asymmetric unit and hydrogen bonding is abundant, creating an extended network. Three of the four dimethylacetamide (DMA) molecules bonded to Nd have various degrees of common structural disorder.
