have been characterized by IR, multinuclear ( (1)H, (13)C (1)H}, (31)P, and (119)Sn) NMR, and single crystal X-ray diffraction studies. The asymmetric unit of 1 is comprised of a tetramer with four crystallographically unique tin atoms. The structure reveals a central eight-membered (Sn-O-S-O) 2 cyclic ring with two exocyclic tin atoms, which results from micro 3-binding of the two methanesulfonate groups
混合配体二有机锡酯,[R 2Sn(OP(O)(OH)Ph)(OS(O)2R(1))] n [R = n-Bu,R(1)= Me(1),n- Pr(2); R = Et,R(1)= Me(3)],是通过在温和的条件下(室温)使锡前体R 2Sn(OR(1))OS(O)2R与等摩尔量的苯基膦酸反应合成的,6-8h,CH 2Cl 2)。它们的特征在于IR,多核((1)H,(13)C (1)H},(31)P和(119)Sn)NMR和单晶X射线衍射研究。1的不对称单元由具有四个晶体学上唯一的锡原子的四聚体组成。该结构揭示了带有两个环外锡原子的中心八元(Sn-OSO)2环状环,这是由于两个甲磺酸酯基团的微3键结合所致。其余的两个磺酸盐是单齿的,并有助于O ... HO(P)的氢键键合。借助于每个锡原子上的氢苯基膦酸酯基团,分子结构扩展为3D配位聚合物,以微2-O 2P模式起作用,并在结构框架中形成一系
