简介:
Three organotin carboxylates based on amide carboxylic acids: (Ph3Sn)2(L1) (1) (L1 ? 3,30-(1,3,5,7- tetraoxo-5,7-dihydropyrrolo[3,4-f]isoindole-2,6(1H,3H)-diyl)dipropionic acid), (Ph3Sn)2(L2)$C7H8 (2) (L2 ? 3,30-(1,3,6,8-tetraoxo-1,3,6,8-tetrahydrobenzo [lmn][3,8]phenanthroline-2,7-diyl)dipropionic acid), [(Ph3Sn)(CH3CH2O)]2(L3) (3) (L3 ? 2,20-(1,3,5,7-tetraoxo-5,7-dihydropyrrolo[3,4-f]isoindole-2,6(1H,3H)- diyl) dibenzoic acid) were synthesized and characterized by elemental analysis, IR, 1H, 13C, 119Sn NMR spectroscopy and X-ray crystallography diffraction analyses. Complexes 1e3 are di-nuclear triphenlytin carboxylates owning “S” shaped monomer structures. Ligands in 1e3 adopt unidentate coordination. Intermolecular hydrogen bonds and Sn$$$O interactions help complexes 1e3 build their supramolecular structures which are discussed in detail. The preliminary antitumor activities of 1e3 against HepG2 cell lines have also been studied.
