Abstract

The asymmtric unit of the title compound, (C27H50N)[Ni(C3S5)2], contains two N-benzyl-N,N-dimethyl­octa­decan-1-aminium cations, [BDA]+, and two [Ni(dmit)2]− anions (dmit = 2-thioxo-1,3-dithiole-4,5-dithiol­ate). The C18 chains in both cations adopt almost ideal extended conformations. The NiIII atoms are coordinated by two S,S′-bidentate ligands, generating NiS4 square planes. Short Ni⋯S [3.734 (2) Å] and S⋯S contacts [3.5438 (15) Å] occur in the crystal structure; if these are considered to be bonding inter­actions, then infinite sheets of anions parallel to (111) arise.
