Abstract

An efficient method was developed for the preparation of three tetraorganodistannoxane complexes, (C2H5)8Sn4Cl2(CH3O)2O2 (1), (CH3)Sn4(C3H4N3S)2(CH3O)2O2 (2) and (C4H9)8Sn4(C3H4N3S)2(CH3O)2O2 (3). All prepared complexes were characterized by infrared, 1H, 13C and 119Sn NMR spectroscopes and elemental analysis. The molecular structure of a representative complex (1) was determined by single-crystal X-ray diffraction. This study showed that 1 lies about a center of inversion and the tetranuclear molecule features a three-ringstaircase Sn4O4 core. The asymmetric unit of 1contains two independent Sn(IV) atoms and a 2D infinite rigid chain structure forms via C-H…Cl interactions between tetranuclear units. Preliminary toxicity test study showed that the organotin(IV) complexes containing triazole groups, 2 and 3 are more toxic than the 1. The results showed that besides the nature and bulkiness of the tin-bound organic groups, the nature of donor ligands that involved in coordination also affects biological behavior of organotin compounds. The reaction details and features were described and discussed.
