摘要

The two Ni^II atoms in the title complex, [Ni2(CN)4(C16H36N4)]·C3H7NO·0.5H2O, are bridged by a cyanide ion. The macrocycle folds around one Ni^II atom, which is five-coordinated in an NiN5 square-pyramidal geometry. The other Ni^II atom is surrounded by the cyanide ions in an NiN4 square-planar geometry. The dimethyl­formamide solvent mol­ecule is disordered over two positions in a 0.62 (1):0.38 (1) ratio and the water mol­ecule is disordered about a center of inversion. The dinuclear mol­ecule and solvent mol­ecules are linked by N—H⋯O, N–H⋯N and O—H⋯O hydrogen bonds, forming a three-dimensional network.
