Tris(2,2′-bipyridine)copper(II) pentacyanidonitrosoferrate(II) methanol disolvate monohydrate

Abstract

The title complex [Cu(C10H8N2)3][Fe(CN)5(NO)]·2CH3OH·H2O, consists of discrete [Cu(bpy)3]2+ cations (bpy is 2,2′-bipyridine), [Fe(CN)5NO]2− anions and solvent molecules of crystallization (two methanol molecules and one water molecules per asymmetric unit). The CuII ion adopts a distorted octahedral environment, coordinated by six N atoms from three bpy ligands. The cation charge is balanced by a nitroprusside counter-anion, which has a slightly distorted octahedral coordination geometry. In the crystal, anions and solvent molecules are involved in O—H...N and O—H...O hydrogen bonds, which form chains along [100]. The cations are located between these chains.
