title: (5,7,7,12,14,14-Hexamethyl-1,4,8,11-tetra-aza-cyclo-tetra-deca-4,11-diene)nickel(II) bis-[O,O'-bis-(4-tert-butyl-phen-yl) dithio-phosphate].
abstract: The title salt, [Ni(C(16)H(32)N(4))](C(20)H(26)O(2)PS(2))(2), comprises a centrosymmetric [Ni(Me(6)[14]dieneN(4))](2+) dication (Me(6)[14]dieneN(4) is 5,7,7,12,14,14-hexa-methyl-1,4,8,11-tetra-aza-cyclo-tetra-deca-4,11-diene) and two O,O'-bis-(4-tert-butyl-phen-yl) dithio-phosphate anions. The Ni(II) ion lies on an inversion centre and displays a slightly distorted NiN(4) square-planar chelation arrangement with four N atoms from the Me(6)[14]dieneN(4) macrocycle. Two S atoms from symmetry-related anions are located in pseudo-axial positions with respect to the Ni(II) ion, with Ni⋯S distances of 3.2991 (7) Å. Inter-molecular N-H⋯S and C-H⋯S hydrogen bonds link the complex cation and pair of anions into a 1:2 type salt.
