采用溶剂热法,丁烷四羧酸(H4L)与水合乙酸钴经配位聚合反应合成了一个新型的双核Co(Ⅱ)聚合物[Co2L(MeOH)(H2O)4]n.nH2O(1),其结构经元素分析和单晶X-射线衍射表征。1属单斜晶系,C2/c空间群,晶胞参数a=2.802 6(3)nm,b=0.816 32(11)nm,c=1.630 1(2)nm,β=119.793(2)°,V=3.236 5(7)nm3,Z=8,Dc=1.925 Mg.cm-3,R1=0.097 5,wR2=0.223 1。1通过H4L桥联形成一维链,通过O-H┈O氢键作用形成了无限延伸的二维网络结构;在1中存在的分子内及分子间氢键使1具有三维网络结构。
A novel binuclear Co (Ⅱ) polymer [Co2L (MeOH) (H2O) 4] n.nH2O (1) was synthesized via the coordination polymerization of butane tetracarboxylic acid (H4L) Its structure was characterized by elemental analysis and single crystal X-ray diffraction. 1 belongs to the monoclinic system with C2 / c space group and the unit cell parameters a = 2.802 6 (3) nm, b = 0.816 32 (11) nm, c = 1.630 1 , V = 3.236 5 (7) nm3, Z = 8, Dc = 1.925 Mg.cm-3, R1 = 0.097 5, wR2 = 0.223 1.1 One-dimensional chains were formed by H4L bridging through OH ┈ O hydrogen bonding Forming an infinitely extended two-dimensional network structure; the intramolecular and intermolecular hydrogen bonds present in 1 have a three-dimensional network structure.
