$^1H, ^{13}C, ^{119}Sn$ NMR, Mass, Mössbauer and biological studies of Tri-,Di- and chlorodiorganotin (IV) carboxylates

The reaction of 2-[(2,3-dimethylphenyl)amino]benzoic acid (HL) with tri- and diorganotin(IV) chlorides yielded complexes of the type $R_3SnL$ and $R_2SnL_2$ (R = $n-C_4H_9$, $C_6H-5$, $C_6H_5CH_2$, $n-C_8H_{17}$). The compounds $R_2SnCIL$ were obtained by a redistribution reaction between $R_2SnL_2$ and $R_2SnCl_2$. All the compounds were characterized by CHN analysis, infrared, multinuclear NMR, mass and Mössbauer spectroscopy. The possible mode of carboxylate group bonding in solid as well as in solution is proposed on the basis of infrared, Mössbauer and NMR ($^1H$, $^{13}C$, $^{119}Sn$) spectroscopy.
