Bis[S-octyl 3-(2-methylpropylidene)dithiocarbaz-ato-j²N³,S]nickel(II)

The central Ni^II atom in the title complex, [Ni(C₁₃H₂₅N₂S₂)₂], is located on an inversion center and adopts a roughly square-planar coordination environment defined by two chelating N,S donor sets of two symmetry-related ligands in a trans configuration. The Ni—N and Ni—S bond lenghts are 1.9193 (14) and 2.1788 (5) A , respectively, with a chelating N—Ni—S bond angle of 86.05 (4). These data are compared with those measured for similar dithiocarbazato ligands that bear n-octyl or n-hexyl alkyl chains. Slight differences are observed with respect to the phenylethylidene derivative where the ligands are bound cis relative to one another.
