(meso-5,5,7,12,12,14-Hexamethyl-1,4,8,11-tetraazacyclotetradecane)nickel(II) bis(O,O′-dibenzyl dithiophosphate)

Abstract

In the title salt-type 1:2 adduct, [Ni(C16H36N4)](C14H14O2PS2)2 or [Ni(tet-a)][S2P(OCH2Ph)2]2, where tet-a is meso-5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane, 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-phenylmethyl) dithiophosphate anions act as counter-ions to balance the charge and they interact 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.
