μ-Cyanido-1:2κ(2) N:C-tricyanido-2κ(3) C-(rac-5,5,7,12,12,14-hexa­methyl-1,4,8,11-tetra­aza­cyclo­tetra­decane-1κ(4) N,N′,N′′,N′′′)dinickel(II) N,N-di­methyl­formamide monosolvate hemi­hydrate

The two Ni(II) atoms in the title complex, [Ni(2)(CN)(4)(C(16)H(36)N(4))]·C(3)H(7)NO·0.5H(2)O, are bridged by a cyanide ion. The macrocycle folds around one Ni(II) atom, which is five-coordinated in an NiN(5) square-pyramidal geometry. The other Ni(II) atom is surrounded by the cyanide ions in an NiN(4) 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.
