以CoCl2.6 H2O和丁二酸(CH2COOH)2、三乙胺为原料,在中温水热反应条件下,合成了一种新型配位聚合物[Co(C5H5N)2(H2O)2(O2CC2H4CO2)]n,并对其进行了X射线单晶衍射和红外光谱测定。晶体数据如下:正交晶系,Pbca空间群,a=11.91940(12)nm;b=8.91440(10)nm;c=15.1025(2)nm;α=90.00;β=90.00;γ=90.00;V=1604.71(3)nm3;Z=4;Dc=1.528 g/cm3;μ=1.101 mm-1;F(000)=764;R1=0.0492,wR2=0.0831。该晶体通过分子间氢键和相互作用的π-π键形成一维的链状结构。
A new coordination polymer [Co (C5H5N) 2 (H2O) 2 (O2CC2H4CO2)] was synthesized by the reaction of CoCl2.6H2O with succinic acid (CH2COOH) 2 and triethylamine at mesophilic hydrothermal conditions. ] n, and its X-ray single crystal diffraction and infrared spectroscopy. The crystal data are as follows: orthorhombic, Pbca space group, a = 11.91940 (12) nm; b = 8.91440 (10) nm; c = 15.1025 (2) nm; = 1604.71 (3) nm3; Z = 4; Dc = 1.528 g / cm3; μ = 1.101 mm-1; F (000) = 764; R1 = 0.0492, wR2 = 0.0831. The crystal through the intermolecular hydrogen bonds and the interaction of π-π bond to form a one-dimensional chain structure.
