3-Methyl-1-(1-phenylethyl)pyridinium bis(1,2-dicyanoethene-1,2-dithiolato)nickelate(III)

Abstract

A new ion-pair complex, (C14H16N)[Ni(C4N2S2)2] or (PhEtPyMe)+[Ni(mnt)2]− [(PhEtPyMe)+ is 1-(1-phenyl­ethyl)-3-methyl­pyridinium and mnt2− is maleonitrile­dithiol­ate], crystallizing with two anions and two cations in the asymmetric unit, has been synthesized. The NiIII atoms exhibit square-planar coordination geometry with four S atoms from two mnt2− ligands. The cations and anions form well segregated columnar stacks along the a axis. Weak Ni⋯S, S⋯S and π–π inter­actions between anions mediate the formation of one-dimensional zigzag chains of NiIII ions.
