Abstract

The complete mol-ecule of the title hydrazine carbodi-thio-ate complex, [Ni(C₁₉H₂₁N₂S₂)₂], is generated by the application of a centre of inversion. The Ni^II atom is N,S-chelated by two hydrazinecarbodi-thio-ate ligands, which provide a trans-N₂S₂ donor set that defines a distorted square-planar geometry. The conformation of the five-membered chelate ring is an envelope with the Ni^II atom being the flap atom. In the crystal, p-tolyl-C-H⋯π(benzene- ⁱ Pr), ⁱ Pr-C-H⋯π(p-tol-yl) and π-π inter-actions [between p-tolyl rings with inter-centroid distance = 3.8051 (12) Å] help to consolidate the three-dimensional architecture. The analysis of the Hirshfeld surface confirms the importance of H-atom contacts in establishing the packing.
