Combination of the hydrochloride salt of cysteamine (1) with HgCl2 in water affords the unique compound, [Hg{S(CH2)2NH3}2](Cl)2 (2) in which the S-Hg-S angle is nearly linear. The ammonium portion of the molecule forms short hydrogen bonding contacts with the sulfur atoms. A related S···H bond is observed in the structure of the free ligand 1 indicating that such bonding does not require the presence of a metal. The compounds were characterized with spectroscopic (1H NMR, IR) and physical techniques (Mp, CH-analysis) as well as X-ray diffractometry.
