Mercury(II) and methylmercury(II) complexes of novel sterically hindered thiolates: sup 13 C and sup 199 Hg NMR studies and the crystal and molecular structures of (MeHg(SC sub 6 H sub 2 -2,4,6-Pr sup i sub 3 )), (Hg(SC sub 6 H sub 4 -2-SiMe sub 3 ) sub 2 ), (Hg(2-SC sub 5 H sub 3 N-3-SiMe sub 3 ) sub 2 ), and (Hg l brace (2-SC sub 6 H sub 4 ) sub 2 SiMe sub 2 r brace ) sub 2

Several series of complexes of the types (MeHg(SR)) and (Hg(SR){sub 2}) have been synthesized, where the ligands are members of new classes of sterically hindered thiolates, including (triorganosilyl)methanethiols, 2-(triorganosilyl)benzenethiols, 3-(triorganosilyl)pyridine-2-thiols, and bis(2-mercaptophenyl) derivatives. Detailed {sup 1}H, {sup 13}C, and {sup 199}Hg NMR studies revealed several general trends. The {sup 199}Hg chemical shifts moved upfield in the order (MeHg(SR)) < (Hg(SCR{prime}R{double prime}R{prime}{double prime}){sub 2}) < (Hg(S-aryl){sub 2}) < (Hg(S-pyridyl){sub 2}). For the (MeHg(SR)) series of complexes, {sup 1}J(Hg-C) correlates with {delta}({sup 13}C(methyl)) and with the type of thiolate ligand. Anomalous behavior is observed for oligomeric species. There is only a limited correlation of {delta}({sup 199}Hg) with steric cone angles for a subset of the complexes. Crystal data for the complexes are reported. 86 refs., 7 figs., 11 tabs.
