Abstract

Two organotin(IV) carboxylates of (E)-3-(2-nitrophenyl) propenoic acid (HL), [Ph 3SnL] n ( 1) and {[Bu 2SnL] 2O} 2 ( 2), have been synthesized. All the complexes were characterized by elemental analysis, FT-IR and NMR ( 1H, 13C) spectroscopy. In addition, the molecular structures of 1 and 2 have been determined by single crystal X-ray diffraction analysis. Complex 1 consisted of a 1D chain polymer and was interconnected by C H⋯π stacking to aggregate in 2D framework. Complex 2 contained a dimeric tetraorganodistannoxane of ladder arrangement and was linked by C H⋯O hydrogen bonds to form a 1D chain. Their antitumor activities were also investigated.
