Abstract Two novel diorganotin(IV) carboxylates: Ph2SnL2 1 and Cy2SnL2 2 (HL = 2-benzoylbenzoic acid), were assembled by dialkyltin oxide (alkyl = phenyl or cyclohexyl) and HL with 1:2 molar ratio. The synthesized complexes have been structurally characterized by elemental analysis, IR, 1H, 13C, 119Sn NMR spectroscopy and X-ray crystallography diffraction analyses. Both 1 and 2 are mono-nuclear dialkyltin carboxylates. The carboxylate groups of HL in 1 and 2 adopt bidentate mode to coordinate with the central Sn atom. 1D, 2D and 3D supramolecular structures formed by intermolecular hydrogen bonds, C-H···π and π···π interactions are discussed in detail. Furthermore, the preliminary luminescent properties of 1 and 2 have been studied.

基于 2-苯甲酰苯甲酸的新型二有机锡 (IV) 羧酸盐：合成、表征、分子结构和发光活性

摘要 两种新型二有机锡(IV)羧酸盐：Ph2SnL2 1 和Cy2SnL2 2 (HL = 2-苯甲酰基苯甲酸)，由二烷基氧化锡(烷基=苯基或环己基)和HL以1:2的摩尔比组装而成。合成的配合物已通过元素分析、IR、1H、13C、119Sn NMR 光谱和 X 射线晶体衍射分析进行结构表征。1和2都是单核二烷基锡羧酸盐。1和2中HL的羧基采用双齿模式与中心Sn原子配位。详细讨论了由分子间氢键、CH…π和π…π相互作用形成的1D、2D和3D超分子结构。此外，还研究了 1 和 2 的初步发光特性。
