Abstract
The phenylmercury(II) derivatives PhHgS2P(OR)2 (R=C2H5, C6H11 and C6H5) have been synthesized. (O,O′-diethyldithiophosphate) phenylmercury(II), C10H15HgO2PS2, crystallizes in the monoclinic space groupP21/c (n° 14) witha=7.330(5),b=18.085(2),c=11.552(4)A,β=105.96(5)°,V=1472.3(6)A3,Z=4,D=2.088 g.cm−3. The mercury atom is coordinated to the phenyl carbon atom and to a ligand sulphur atom in an almost linear arrangement (C-Hg-S angle, 176.0(2)°. The ligand is almost monodentate, its second sulphur atom only being involved in a weak secondary intermolecular bond.IR and Raman studies of the other two compounds suggest the same coordination scheme. Positive ion FAB and13C,31P and199Hg NMR spectra are also discussed.
