Synthesis and Characterization of Triphenyltin(IV) Carboxylates with Isophthalic Acid and Benzoic Acid Derivatives: X-ray Crystal Structures of 1D Supramolecular Chains



The reaction of triphenyltin(IV) hydroxide with the isophthalic acid and benzoic acid derivatives, 5-(1,3-dioxo-1,3-dihydro-isoindol-2-yl)-isophthalic acid (H2L1) and 4-(1,3-dioxo-1,3-dihydro-isoindol-2-yl)-benzoic acid (HL2) yielded the complexes [(SnPh3)2L1] (1) and [(SnPh3)L2] (2). All complexes were characterized by elemental analysis and FT-IR and NMR (1H, 13C, 119Sn) spectroscopy. Interestingly, the supramolecular structures of 1 and 2 are found to consist of 1D molecular chains built up by intermolecular C–H···O hydrogen bonds. Their thermal stabilities were also investigated.
