1-Butyl-3-(1-naphthyl-meth-yl)benzimidazolium hemi{di-?-iodido-bis-[diiodidomercurate(II)]} dimethyl sulfoxide monosolvate.

ABSTRACT: In the title compound, (C(22)H(23)N(2))[Hg(2)I(6)](0.5)·(CH(3))(2)SO, the 1-butyl-3-(1-naphthyl-meth-yl)benzimidazolium anion lies across a centre of inversion. The dihedral angle between the benzimidazolium and naphthalene ring systems is 81.9?(3)°. In the crystal structure, ?-? stacking inter-actions are observed between the imidazolium ring and the unsubstituted benzene ring of the naphthalene ring system, with a centroid-centroid separation of 3.510?(5)?Å. In the centrosymmetric anion, the Hg(II) atoms are in a distorted tetrahedral coordination. The dimethyl sulfoxide solvent mol-ecule is disordered over two sites with occupancies of 0.615?(9) and 0.385?(9).
