The complex 1, [systematic name 1,2,3,4-di-μ2-hydroxyl-1,4-diacetic-1,1,2,2,3,3,4,4-octa-n-butyl-di-μ3-oxo-tetratin(Ⅳ)], [Sn4(C6H5)8(OH)2O2(CH3COO)2], was synthesized and characterized by elemental analysis, 1H NMR, FTIR spectroscopy and X-ray diffraction single crystal struscture analysis. The symmetric dimer with a hydroxy bridged ladder consists of a central Sn2O2 ring with two additional adjacent Sn2(OH)O four-membered rings. The Sn, O and OH atoms are approximately coplanar; the Sn atoms exhibit a distorted trigonal-bipyramidal coordination configuration. The 2D layer is exhibited with chanels formed by the hydrogen-bonded (C-H…O). The antibacterial activity was preliminarily studied. CCDC: 666441. 相似文献

辣椒素同系物合成、辣度及海洋生物防污性能研究 总被引:1,自引:0,他引:1
合成了十种辣椒碱同系物,用感官评定的方法对其辣度进行了测定,并将它们的结构与辣度进行了对比,探讨了影响辣椒碱同系物辣度的结构因子.选取其中辣度较大的四种辣椒碱同系物作为海洋生物防污涂料的驱赶剂,考察了它们的海洋生物防污性能.结果表明,辣椒碱和二氢辣椒碱都具有良好的防污性能,二者不相上下.降二氢辣椒碱和壬酸香草胺的防污性能与辣椒碱和二氢辣椒碱有明显区别.仅以辣椒碱或二氢辣椒碱为驱赶剂,且其含量仅为0.1%的情况下,漆膜也表现出较好的防污性能,这为研发新型的、环保的、不含氧化亚铜的防污涂料提供了新思路. 相似文献
