Abstract: The Schiff base ligand in the title complex, [Ni(C₁₅H₂₂N₃S₂)₂], lost a proton from its tautomeric thiol form and coordinated to Ni(II) via the mercapto S and -N atoms. The geometry around the Ni atom is square planar with two equivalent Ni-N and Ni-S bonds. The two phenyl rings and the coordination moieties are in one plane forming an extensive electronic delocalization system. The structure is governed by C-HS and C-HN hydrogen bonds, leading to the formation of centrosymmetric dimers.
