1-(2-Chlorobenzyl)-2-methylpyridinium bis(maleonitriledithiolato)nickelate(III)

C.-L. Ni and M.-G. Liu

Abstract: The title compound is a new ionic complex, (C₁₃H₁₃ClN)[Ni(C₄N₂S₂)₂] or [ClBzPyMe][Ni(mnt)₂] [where ClBzPyMe is 1-(2-chlorobenzyl)-2-methylpyridinium and mnt is maleonitriledithiolate]. In the anion the Ni^III atom is coordinated by the four S atoms of two mnt^2- ligands and exhibits the expected square-planar coordination geometry. In the [ClBzPyMe]⁺ cation the benzene and pyridine rings are twisted with respect to the C/C/N plane incorporating the methylene C atom that links them. The [Ni(mnt)₂]^- anions and [ClBzPyMe]⁺ cations stack into well segregated columns along the a axis, and the Ni^III ions form a one-dimensional zigzag chain through weak NiS, SS, and - interactions.
