title: (meso-5,5,7,12,12,14-Hexamethyl-1,4,8,11-tetra-azacyclo-tetra-deca-ne)nickel(II) bis-(O,O'-dibenzyl dithio-phosphate).
abstract: In the title salt-type 1:2 adduct, [Ni(C(16)H(36)N(4))](C(14)H(14)O(2)PS(2))(2) or [Ni(tet-a)][S(2)P(OCH(2)Ph)(2)](2), where tet-a is meso-5,5,7,12,12,14-hexa-methyl-1,4,8,11-tetra-azacyclo-tetra-decane, the [Ni(tet-a)](2+) complex cation exhibits a relatively undistorted square-planar geometry about the Ni atom, which lies on an inversion centre and is coordinated by four macrocyclic N atoms. The two O,O'-bis-(2-phenyl-meth-yl) dithio-phosphate anions act as counter-ions to balance the charge and they inter-act with the complex through N-H⋯S hydrogen bonds. Important geometric data include Ni-N distances of 1.958 (3) and 1.963 (3) Å.
