Triorganotin coordination polymers based on three dicarboxylate ligands containing flexible S S bonds: synthesis, structures and in vitro anti-tumor activity

Six new triorganotin complexes, [(R3Sn)2(O2CC5H3NS)2]n (R = Me: 1; n-Bu: 2), [(R3Sn)2(O2CC6H4S)2]n (R = Me: 3; n-Bu: 4), [(R3Sn)2(O2CCH2S)2]n (R = Me: 5; n-Bu: 6) have been obtained by the reaction of R3SnCl (R = Me, n-Bu) with the corresponding dicarboxylate ligands (H2L1 = 6,6’-dithiodinicotinic acid, H2L2 = 2,2’-dithiodibenzoic acid, H2L3 = dithiodiglycolic acid). All the compounds were characterized by elemental analysis, IR, NMR, and X-ray...
