The new sodium bis(1-methyl-1H-imidazol-2-ylthio)acetate, Na((S-tim)2CHCO2), has been prepared in ethanol solution using 2-mercapto- 1-methylimidazole, dibromoacetic acid and NaOH. New di- and tri-organotin(IV) derivatives have been synthesized from reaction betweenSnRnCl4-n (R = Ph, Cy and nBu, n= 2–3) acceptors and Na((S-tim)2CHCO2). Complexes of the type ((K1O-(S-tim)2CH-CO2)SnR3) and related decarboxylated species((K2N,N-(S-tim)2CH2)SnR2Cl2) have been obtained and characterized by elemental analyses, FT-IR, ESIMS and multinuclear (1H, 13C and 119Sn) NMR spectral data. The adduct ((K1O-(S-tim)2CH-CO2)Sn(H2O)(C4H9)3) was characterized by single crystal X-ray studies. The dichloromethane reaction solution of (K1O-((S-tim)2CHCO2)Sn(C6H5)3) was re-crystallized and the decarboxylated species(((S-tim)2CH2)SnCl(H2O)(C6H5)3) was obtained as a crystalline solid and characterized by X-ray crystallography.

New silver(I) complexes have been synthesised from the reaction of AgNO3, monodentate PR3 (PR3 = P(o-tolyl)3, P(m-tolyl)3, P(ptolyl) 3, P(p-C6H4F), SeP(C6H5)3) or bidentate tertiary (dppe = bis(diphenylphosphane)ethane, dppf = 1,10-bis(diphenylphosphane)ferrocene) phosphanes and potassium dihydrobis(3-nitro-1,2,4-triazolyl)borate, K[H2B(tzNO2)2]. These compounds have been characterized by elemental analyses, FT-IR, ESI-MS and multinuclear (1H and 31P) NMR spectral data. The adduct {[H2B(tzNO2)2]Ag[P(m-tolyl)3]2} has been characterized by single crystal X-ray studies. In the former, the H2B(tzNO2)2 acts as a monodentate ligand utilizing the coordinating capability of only one of the additional (exo-) ring nitrogens to complete the coordination array about the silver atom.
