Bis[tris(ethane-1,2-diamine)nickel(II)] octacyanidomolybdate(IV) dihydrate

Abstract

The title complex, [NiII(C2H8N2)3]2[MoIV(CN)8]·2H2O, crystallized from a mixture of ethane-1,2-diamine (en), octacyanomolybdate(IV), [Mo(CN)8]4−, and the transition metal ion Ni2+. In the crystal structure, the Mo polyhedron has a square-antiprismatic shape, while the geometry around the Ni atom is distorted octahedral. The complex ions and water molecules are linked by hydrogen bonds.
