Hexadecyl­trimethyl­ammonium bis­(2-thioxo-1,3-dithiole-4,5-dithiol­ato-κ2 S4, S5)nickelate(III).

In the title complex, (C19H42N)[Ni(C3S5)2], the Ni atom is coordinated by four 2-thioxo-1,3-dithiole-4,5-dithiol­ate (dmit) S atoms. The [Ni(dmit)2]− monoanion has a planar geometry, with the central Ni atom and the four coordinated S atoms forming an NiS4 square plane. There are S⋯S inter­molecular contacts in the crystal structure. [ABSTRACT FROM AUTHOR]
