Di- and tri-organotin(IV) complexes derived from aryltelluronic acids: Synthesis, structural characterization and in vitro cytotoxicities

Reactions of R2SnCl2 (R = Me) or R3SnCl (R = Me, Ph) with the respective dinuclear aryltellurinic acid (H6L1 = [3,4-Me2C6H3TeO(OH)3]2 and H6L2 = [3,5-Me2C6H3TeO(OH)3]2) afforded two types of aryltelluronic organotin esters: [R2Sn(CH3OH)(R2SnCl)]2L (L1 = [3,4-Me2C6H3TeO4]2, R = Me: 1; L2 = [3,5-Me2C6H3TeO4]2, R = Me: 4) and [(R3Sn)2H]2L (L1 = [3,4-Me2C6H3TeO4]2, R = Me: 2, R = Ph: 3; L2 = [3,5-Me2C6H3TeO4]2, R = Me: 5, R = Ph: 6).
