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-HS hydrogen bonds. Important geometric data include Ni-N distances of 1.958 (3) and 1.963 (3) Å.
