Synthesis and Characterisation of μ-Oxy-bis[triphenylbismuth(V)] Dicarboxylates and Halo-Carboxylates

摘要

Several unknown μ-oxybis[triphenylbismuth]dicarboxylates and μ-oxy-bis[triphenylbismuth]chloro-carboxylates of the general formula Ph3Bi(L)-O-Bi(L)Ph3 and Ph3Bi(Cl)-O-Bi(L)Ph3, respectively have been synthesised by the metathetieal reactions of μ-oxybis-[triphenylbismuth]dichloride reactions and silver salts of corresponding carboxylic acids in 1 ;2 and 1:1 ratio [where L= 2-pyrazine carboxylic acid, p-methoxy mandelic acid, salicylic acid, benzillic acid and p-(trifluoromethyL)mandelic acid)]. The newly synthesized bismuth derivatives have been characterized on the basis of melting point, elemental analysis, IR ~1H and ~(13)C NMR spectra. The molecular weight and conductivity data indicate the monomeric and non electrolytic behaviour in solution.
