Synthesis, structure and in vitro cytostatic activity study of the novel organotin(IV) derivatives of p -aminobenzenesulfonic acid

Four new p-aminobenzenesulfonate organotin complexes, [(n-Bu3Sn)(O3SC6H3-NH2-4)]n (1), [(n-Bu2Sn)4(O)2(OH)2(O3SC6H4-NH2-4)2] (2), [(Me2Sn)4(O)2(OH)2(O3SC6H4-NH2-4)2] (3) and [{(n-BuSn)12O14(OH)6}(O3SC6H4-NH2-4)2·3C4H8O2] (4·diox), were synthesized by reaction of p-aminobenzenesulfonic acid with tributyltin oxide, dibutyltin oxide, dimethyltin oxide and monobutyltin oxide, respectively. These complexes were characterized by elemental analysis,...
