“…Cadmium and mercury complexes of general formula [M(RpymS) 2 ] (M = Cd and Hg; R = 4-CF 3 , 4,6-CF 3 ,Me and 4,6-CF 3 ,Ph) were easily prepared in reasonable yields by a simple, one-step electrochemical method. Mixed complexes of cadmium with 2,2Ј-bipyridine or 1,10-phenanthroline were also obtained by addition of the correspond- ing coligand to the cell.…”

The electrochemical oxidation of anodic metal (cadmium or mercury) in a cell containing an acetonitrile solution of the appropriate pyrimidine‐2‐thione (RpymSH) affords complexes [M(RpymS)2] (M = Cd, Hg; R = 4‐CF3, 4,6‐CF3,Me and 4,6‐CF3,Ph). When 2,2'‐bipyridine (bipy) or 1,10‐phenanthroline (phen) was added to the electrolytic cell, adducts of cadmium and compounds with these coligands were obtained. All the compounds have been characterised by microanalysis, IR spectroscopy and, in the case of the compounds that were sufficiently soluble, by 1H, 13C and 199Hg NMR spectroscopy. The compounds [Cd(4‐CF3pymS)2] (1), [Cd(4,6‐CF3MepymS)2(bipy)] (4), [Cd(4,6‐CF3PhpymS)2(phen)] (6) and [Hg(4,6‐CF3MepymS)2] (8) were also characterised by X‐ray diffraction. Compound 1 presents a polymeric structure with the polymer chains interconnected by intermolecular C–H···N interactions. Compounds 4 and 6 adopt mononuclear structures, with weak inter‐ and intramolecular C–H···π interactions, as well as π–π stacking interactions for compound 6. Compound 8 also presents a mononuclear structure with intermolecular π–π interactions between the pyrimidine rings and additional weak Hg···Hg contacts (3.484 Å). (© Wiley‐VCH Verlag GmbH & Co.

“…( Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004) markable observation is that it can bind one to four metals giving rise to polymetallic materials. [9,12] This unusual property of pyridine-2-thiolates prompted us to investigate pyridine-2-sulfonates, which are extensions of pyridine-2-thiones involving oxidation of sulfur at the 2-position of the pyridine rings. These pyridine-2-sulfonates possess one N and three O atoms (N, 3O donor set) which could provide several possibilities for coordinative and other types of bonding interactions.…”

“…[17][18][19][20][21][22][23][24][25][26] Binuclear structures 4 containing three ligands, can probably be explained by formation of adducts with participation of coordinatively nonsaturated metals in binuclear structures 3. Table 1 shows the dependence between ion composition, ligand nature and electron configuration of the complex-forming metals.…”

Novel ligand systems -azomethinic derivatives of 1-amino-3-methyl-1,3-dihydrobenzoimidazole-2-thione and o-tosylamino(hydroxy)benzaldehydes -are synthesized as a result of a multistage procedure and are evaluated. Study of the coordination activity of these compounds has shown that they form complexes ML 2 with transition d-elements containing MN 4 S 2 and MN 2 O 2 S 2 coordination units in solid and in solution. Electrospray mass-spectrometry results show the possibility of formation of M 2 L 2 and M 2 L 3 complexes in the vapor phase.
