The reactions of 2,2′-selenodiacetic acid and the corresponding organotin(iv) chloride with sodium ethoxide in ethanol, or via a solvothermal synthetic route, have afforded four organotin polymers, namely, [(Me3Sn)2Se(CH2COO)2]n (1), [(Me2Sn)2Se(CH2COO)2(μ3-O)]n (2), [(Bu3Sn)2Se(CH2COO)2]n (3), and [(Bu2Sn)Se(CH2COO)2]n (4). All the complexes were fully characterized by elemental analysis, FT-IR, NMR (1H, 13C, and 119Sn) spectroscopy and single crystal X-ray diffraction analysis. The structural analysis reveals that complex 1 is a 2D-polymer containing interconnected 24-membered (Sn4O8C10Se2) macrocyclic rings. Unlike complex 1, the 2D polymer structure of complex 2 is made up of the typical ladder tetraorganodistannoxane unit containing 32-membered (Sn4O8C16Se4) macrocyclic rings. Complex 3 is a 3D corrugated polymeric structure in which the deprotonated dicarboxylic acid acts as a tetradentate ligand by four oxygen atoms. Complex 4 is a 1D zigzag coordination polymer and the tin coordination geometry is described as skewed-trapezoidal bipyramidal. In particular, preliminary cytotoxic assessments of the involvement of complex 4 in the apoptotic death of MDA cells were conducted, and the results revealed that the antiproliferative and proapoptotic effect of complex 4 in MDA cells prominently contributed to the overload of intracellular ROS levels and the dysfunctional depolarization of mitochondrial membranes.

The electrochemical preparation of telluride, selenide and sulfide ions was carried out in NaOH aqueous solution, using a two compartment cell. Organochalcogenides were prepared from halogenated compounds in a two-step procedure. The monochalcogenides were obtained as the major products in good yields.
