During the process of crystallization of newly synthesized heterobimetallic complexes [(Ph3P)2Cu(μ-SCOR)2Hg(SCOR)] [R = Ph (1), th (thiophene) (2)] Hg(II) thiocarboxylate complexes were isolated. In chloroform/diethyl ether a phosphine migration led to the formation of Hg(Ph3P)(SCOPh)2 (3) and Hg(Ph3P)(SCOth) 2 (4) while in chloroform/n-hexane the binary Hg(II) complexes, Hg(SCOPh)2 (5) and Hg(SCOth)2 (6) were isolated. In another reaction a heterobimetallic complex, Hg(SCOPh)2TiCl 4 (7) was obtained as the end product. Molecular structures of 3, 4 and 6 were studied by single crystal X-ray diffraction. The crystals of 4 provided an interesting example of polytopal isomerism. Structures and electronic transitions have been explained on the basis of DFT calculations.
Synthesis, NMR (13C, 111Cd, 199Hg) spectra and structures of (Ph4As)2[Hg2Cl4(SC(O)Ph) 2] and (Ph4As)2[CdCl4Hg(SC(O)Ph)2]

Combination of Ph4AsCl · H2O, Hg(SC(O)Ph)2 and HgCl2 or CdCl2 · 2.5H2O in the required stoichiometric ratio gives (Ph4As)2[MCl4Hg(SC(O)Ph)2], M = Hg (1) or Cd (2). Crystals of 1 were also isolated in an unsuccessful attempt to prepare the complex (Ph4As)[Na{Hg(SC(O)Ph)3}2]. X-ray crystallographic analyses of 1 and 2 show both to contain a Hg(II) bonded to two thiobenzoate ligands with a near-linear S - Hg - S skeleton. The S - Hg - S angle is 174.9(2)° in 1 and 175.4(1)° in 2. In each, the Hg(SC(O)Ph)2 moiety is involved in weak interactions with two chlorine atoms from [MCl4]2-. Mercury-199 and 111Cd NMR spectral studies indicate that the Hg(SC(O)Ph)2 remains intact in solution, and that scrambling or transfer of ligands between the linear and tetrahedral metal centres does not occur. Carbon-13 and 199Hg NMR data are reported for Hg(SC(O)Ph)2.

It has been found that the reaction of diphenylmercury with an equimolar amount of thio- or dithio acids gave the corresponding phenylmercury thio- (1) or dithiocarboxylates (2), quantitatively, which further react with thio- or dithio acids to give mercury bis(thio-) (3) or bis(dithiocarboxylates) (4).The phenylmercury dithio salts (2) were found to be the very useful thioacylating agents for primary and secondary amines.The reaction of mercury bis(thiocarboxylates) (3) with dithiocarboxylic acids gave the unsymmetrical thio- and dithiocarboxylic acid mercury salts (5) in good yield. - Keywords: Phenylmercury Thiocarboxylates
