New phenylmercury(II) complexes of the form [PhHg(L1), PhHg(L2) and PhHg(L3)] (L1 = methyl-3-hydroxy-3-(p-methoxyphenyl)-2-propenedithioate (1), L2 = methyl-3-hydroxy-3-(p-bromophenyl)-2-propenedithioate (2) and L3 = methyl-3-hydroxy-(3-pyridyl)-2-propenedithioate (3)) have been synthesized and characterized by elemental analysis, IR, UV-Vis, 1H and 13C NMR. The crystal structures of 1–3 reveal a linear geometry about the mercury atom via ipso-C and S11 atoms. 1 and 2 exhibited O,S-coordination whereas 3 preferred S,S-coordination.

Two new heterobimetallic phenylmercury(ii) dithiocarbamate complexes incorporating the ferrocenyl moiety (C(5)H(5))Fe(C(5)H(4)) (Fc), namely PhHgS(2)CN(CH(2)Fc)CH(2)C(5)H(4)N, (1) and PhHgS(2)CN(CH(2)Fc)CH(2)C(4)H(3)O, (2) have been prepared and characterized by elemental analysis, UV-Vis, IR, (1)H and (13)C NMR spectroscopies. The crystal structures of 1 and 2 showed a linear core at the Hg(ii) centre of the molecule, bound by the sulfur atom of the dithiocarbamate ligand and carbon atom of the aromatic ring. Weak intermolecular HgS interactions form "head-to-tail" dimers in the cases of 1 and 2.

A series of new heterobimetallic phenylmercury(II) dithiocarbamate complexes incorporating the ferrocenyl moiety (C(5)H(5))Fe(C(5)H(4)) (Fc), namely PhHgS(2)CN(CH(2)Fc)CH(2)C(6)H(5), (1), PhHgS(2)CN(CH(2)Fc)CH(CH(3))(2), (2), PhHgS(2)CN(CH(2)Fc)(CH(2))(3)CH(3), (3) and [PhHgS(2)CN(CH(2)Fc)](2)(CH(2)C(6)H(4)CH(2)), (4) have been prepared and characterized by elemental analysis, UV-Vis, IR, (1)H and (13)C NMR spectroscopies. The crystal structures of 1, 2 and 4 showed a linear core at the Hg(II) centre of the molecule, bound by the sulfur atom of the dithiocarbamate ligand and carbon atom of the aromatic ring. Weak intermolecular Hg.

A series of new phenylmercury(II) dithio complexes [PhHg(Bun2dtc)] (; Bun2dtc-=di-n-butyldithiocarbamate), [PhHg(morphdtc)] (; morphdtc-=morpholinedithiocarbamate), [PhHg(Bz2dtc)] (; Bz2dtc-=dibenzyldithiocarbamate), [PhHg(methoxethxant)] (; methoxethxant-=2-methoxyethylxanthate) [(PhHg)2NED] (; NED2-=1-nitroethylene-2,2-dithiolate) and [(PhHg)2CDC] (; CDC2-=cyanodithioimidocarbonate) have been prepared and characterized by elemental analysis, UV-Vis, IR, 1H and 13C NMR spectra and mass spectrometry. The crystal structures of , and showed a linear Hg(II) core at the center of the molecules. The weak intra- and intermolecular HgS interactions provide a molecular chain framework.
