title: (meso-5,5,7,12,12,14-Hexamethyl-1,4,8,11-tetra-aza-cyclo-tetra-deca-ne)nickel(II) bis-[O,O'-(1,2-phenyl-ene) dithio-phosphate].
abstract: In the crystal structure of the title compound, [Ni(C(16)H(36)N(4))](C(6)H(4)O(2)PS(2))(2), the Ni(II) cation is located on a center of inversion and is chelated by the folded tetra-amine macrocycle ligand in a slightly distorted NiN(4) square-planar geometry. Two symmetry-related O,O'-(1,2-phenyl-ene)dithio-phosphate anions are located on either side of the Ni(II) cation, with Ni⋯S of 3.9558 (5) Å, and link to the tetra-amine macrocycle ligand via N-H⋯S hydrogen bonding.
