Synthesis, Characterization and In vitro Antitumour Activity of Novel Organotin Derivatives of 1,2- and 1,7-Dicarba-Closo-dodecaboranes.

Several organotin derivatives of 1,2- and 1,7-dicarba-closo-dodecaboranes were synthesized and characterized by (119)Sn Mössbauer, (1)H, (13)C and (119)Sn NMR spectroscopy. Their antitumour activities in vitro against cancerous cell lines of human origin are reported.
