Crystal structure of (Ph4P)[Hg(SPh)2Br]:: Synthesis, characterization and structure analysis

The complex (Ph4P)[Hg(SPh)(2)Br] has been prepared and the crystal structure has been determined. The complex crystallized in the triclinic space group P (1) over bar with a = 9.607(5), b = 10.120(5), c = 17.071(8) angstrom, alpha = 96.00(3), beta = 100.36(2), gamma = 90.42(3)degrees, V = 1623(2) angstrom(3), D-c = 1.71 g cm(-3), mu = 6.153 cm(-1), F(000) = 816 and Z = 2. The anionic complex [Hg(SPh)(2)Br](-) is the monomer with distorted trigonal planar geometry. It contains relatively strongly bonded two thiolate ligands with a weaker bonding bromide ion. The crystal structure demonstrates a supramolecularity represented by nonconventional Br center dot center dot center dot H-C(pi) hydrogen bonds as well as aryl center dot center dot center dot aryl [C(pi)-H center dot center dot center dot C(pi)] interactions. The Ph4P+ cations are forming recognized extended supramolecular motifs of phenyl embraces.
