The molecular structure of sodium ethylmercury thiosalicylate (also known as thimerosal and Merthiolate) and related arylthiolate mercury alkyl compounds, namely PhSHgMe and PhSHgEt, have been determined by single crystal X-ray diffraction. 1H

The susceptibility of two-coordinate mercury alkyl compounds of the type X - Hg - R (where X is a monodentate sulfur donor) towards protolytic cleavage has been investigated as part of ongoing efforts to obtain information relevant to understanding the me

Full title: Mercury(II) and methylmercury(II) complexes of novel sterically hindered thiolates: 13C and 199Hg NMR studies and the crystal and molecular structures of [MeHg(SC6H2-2,4,6-Pri3)], [Hg(SC6H4-2-SiMe3)2], [Hg(2-SC5H3N-3-SiMe3)2], and [Hg{(2-SC6H4)2SiMe2}]2. Several series of complexes of the types [MeHg(SR)] and [Hg(SR)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 1H, 13C, and 199Hg NMR studies revealed several general trends. The 199Hg chemical shifts moved upfield in the order [MeHg(SR)] 2] 2] 2]. For the [MeHg(SR)] series of complexes, 1J(Hg-C) correlates with δ(13C(methyl)) and with the type of thiolate ligand. Anomalous behavior is observed for oligomeric species. There is only a limited correlation of δ(199Hg) with steric cone angles for a subset of the complexes. Crystal data are as follows.

Multinuclear nmr (1H, 77Se, 111/113Cd, 119Sn, 199Hg, as appropriate) has been used to study Y(1-) - EPh(1-) exchange in Me2CO or MeCN between (RnM'Y (RnM' = Ph3Sn or MeHg; Y = Cl, Br, I, NCO, or NCS) and the adamantane-like anions (2-) (E = S, M = Zn, Cd, or Co; E = Se, M = Zn or Cd), as their tetraalkylammonium salts.Quantitative terminal substitution of the clusters occurs in most cases, giving 4-x(MY)x>(2-) (x = 1-4).However, reaction is incomplete for M = Cd, E = S or Se, RnM'Y = Ph3SnNCO or Ph3SnNCS and for M = Zn or Co, E = S, RnM'Y = MeHgI.Differences in the extents of reaction for Ph3SnY and MeHgY are consistent with the position of equilibrium in MeHgY:Ph3SnEPh mixtures.Group interchange provides a convenient alternative synthesis of the known halogen-substituted clusters (2-) (M = Zn or Cd, Y = Cl, Br, or I; M = Co, Y = Cl), and the first syntheses of (2-) (Y = Br or I) and various pseudohalogen-substituted adamantanoid anions.The nuclei used for full direct nmr characterization of the new clusters in solution were: 77Se and 113Cd for 4-x(CdY)x>(2-) (x = 1-4; Y = NCO or NCS); 77Se for 4-x(ZnY)x>(2-) (x = 1-4, Y = NCO or NCS); 113Cd for 4-x(CdY)x>(2-) (x = 1-4; Y = NCO or NCS); 1H for (2-) (Y = Br, I, NCO, or NCS).The first solution 1H nmr spectrum of (2-) is also reported.
