Multinuclear NMR and Mössbauer spectroscopy have been carried out for d- and triorganotin carboxylates derived from 3-(-2-furanyl)-2-propenoic acid. Their spectroscopic characterization showd that triorganotin carboxylates are either 4-coordinate monomers or 5-coordinate polymers with bridging carboxylate groups. Although a polymeric structure is favoured for most compounds in the solid state, the
已对衍生自3-(-2-呋喃基)-2-丙酸的d-和三有机锡的羧酸盐进行了多核NMR和Mössbauer光谱分析。他们的光谱特征表明三有机锡羧酸盐是具有桥联羧酸根基团的4-配位单体或5-配位聚合物。尽管大多数固态化合物都倾向于采用聚合物结构,但溶液研究表明它们在非配位溶剂中以单体4配位形式存在。通式为R 2 Sn(OOCCHCHC 4 H 3 O)2和二聚体[(R 2 SnOOCCHCHC 4 H 3 O)2 O] 2的二有机锡羧酸盐在非配位溶剂中,它们是五配位的,而在固相中,分子内或分子间的相互作用是可能的。此外,我们报告了二聚二锡氧烷中羧酸根阴离子的通量行为。这些有机锡羧酸盐的生物活性证明它们是强大的杀菌剂。
