The two Ni-II atoms in the title complex, [Ni-2(CN)(4)-(C16H36N4)]center dot C3H7NO center dot 0.5H(2)O, 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 center dot center dot center dot O, N-H center dot center dot center dot N and O-H center dot center dot center dot O hydrogen bonds, forming a three-dimensional network.
