title: N-Benzyl-N,N-dimethyl-octa-decan-1-aminium (2-thioxo-1,3-dithiole-4,5-dithiol-ato-κ(2)S(4),S(5))nickelate(III).
abstract: The asymmtric unit of the title compound, (C(27)H(50)N)[Ni(C(3)S(5))(2)], contains two N-benzyl-N,N-dimethyl-octa-decan-1-aminium cations, [BDA](+), and two [Ni(dmit)(2)](-) anions (dmit = 2-thioxo-1,3-dithiole-4,5-dithiol-ate). The C(18) chains in both cations adopt almost ideal extended conformations. The Ni(III) atoms are coordinated by two S,S'-bidentate ligands, generating NiS(4) 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 inter-actions, then infinite sheets of anions parallel to (111) arise.
