文摘

A series of organotin carboxylates based on (E)-3-(3-nitrophenyl) acrylic acid (HL), namely {[Ph₃SnL]路0.5C₆H₆}_n (1), [(Ph₃Sn)₂O(L)(Ph₃Sn)(L)]_n (2) and [Bu₂LSnOSnLBu₂]₂ (3), have been synthesized. All the complexes have been characterized by elemental analysis, IR, ¹H NMR spectroscopy and X-ray diffraction analyses. The structural analyses show that complexes 1-2 adopt 1D polymeric chain structures generated by the bridging carboxylate ligands and the five-coordinated tin centers. The structure of complex 3 is centro-symmetric and features a central rhombus Sn₂O₂ unit with two additional tin atoms linked at the O atoms. In addition, the antitumor activity of complex 3 has been studied.
