摘要
配位聚合物由于在分子识别、催化、光电性质和磁性等方面表现出独特性能.在新功能材料的开发中显示了诱人的应用前景,近年来。设计和组装具有一维、二维和三维有序结构的配位聚合物已成为超分子化学研究中最活跃的领域之一。为了构筑具有特殊拓扑结构的多维配位聚合物。
A complex {[Co(4,4′-bipy)(H2O)4]·(α-Furacryli cacid)2·(H2O)}n, with a-furacrylic acid, 4,4'-bipy and cobaltous chloride hexahydrate has been synthesized by means of hydrothermal way and characterized. Crystal data for this complex: monoclinic, space group P21/c, a=l. 147 0(2) nm, b=1.099 9(2) nm, c=l. 111 1(2) nm,/3=97.829(3)°, V=1.388 7(5) nm^3, De=1.429 g.cm^-3, Z=2,/z(Mo Ka)=0.682 mm^-1, F(000)=622, S=1.025, R1=0.035 8, wR2=0.086 1. The crystal structure shows that the cobalt(Ⅱ) ion is coordinated with two nitrogen atoms of two 4,4'-bipy molecules and four oxygen atoms from four water molecules, respectively, giving a distorted octahedral coordination geometry. Adjacent cobalt(Ⅱ) ions are bridged by 4,4'-bipy groups, resulting in a 1D chain The adjacent Co(Ⅱ)-Co(Ⅱ) distance is 1.147 0 nm. The cobalt(Ⅱ) ion isn't coordinated with a-Furacrylic complex molecules form 2D structure through hydrogen was also investigated. CCDC: 648243. structure. acid. The bonds.
