| Abstract: Reaction of 4-(4-pyridylmethylthio)benzoic acid with (Ph3Sn)2O and Cy3SnOH (Cy=cyclohexyl) yielded triphenyltin 4-(4-pyridylmethylthio)benzoate (1) and tricyclohexyltin 4-(4-pyridylmethylthio)benzoate (2), respectively. Their crystal structures were determined by single-crystal X-ray diffraction analysis. The crystal of 1 belongs to the monoclinic system, space group P21/n with a=1.0231(5) nm, b=1.6300(8) nm, c=1.5849(8) nm, β=106.417(11)°, V=2.535(2) nm3, Z=4, Dc=1.557 g·cm-3, μ=1.120 mm-1, F(000)=1200, R1=0.0655 and wR2=0.1427. Complex 2 crystallizes with a molecule of water. Its crystal belongs to the monoclinic system, space group P21/c with a=1.0195(2) nm, b=2.1129(4) nm, c=1.4411(3) nm, β=103.847(3)°, V=3.0140(11) nm3, Z=4, Dc=1.389 g·cm-3, μ=0.948 mm-1, F(000)=1312, R1=0.0237 and wR2=0.0540. Complex 1 shows a polymeric chain structure, while complex 2 displays an infinite 2Dnetwork through intermolecular O-H…O and O-H…N hydrogen bonds. The cytotoxic activity of these two complexes for A549, Bel-7402 and Hela cells in vitro was tested. |
