(5,7,7,12,14,14-Hexamethyl-1,4,8,11-tetraazacyclotetradeca-4,11-diene)nickel(II) bis[O,O′-bis(4-tert-butylphenyl) dithiophosphate]

Abstract

The title salt, [Ni(C16H32N4)](C20H26O2PS2)2, comprises a centrosymmetric [Ni(Me6[14]dieneN4)]2+ dication (Me6[14]dieneN4 is 5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradeca-4,11-diene) and two O,O′-bis(4-tert-butylphenyl) dithiophosphate anions. The NiII ion lies on an inversion centre and displays a slightly distorted NiN4 square-planar chelation arrangement with four N atoms from the Me6[14]dieneN4 macrocycle. Two S atoms from symmetry-related anions are located in pseudo-axial positions with respect to the NiII ion, with Ni...S distances of 3.2991 (7) Å. Intermolecular N—H...S and C—H...S hydrogen bonds link the complex cation and pair of anions into a 1:2 type salt.
