摘　　要：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 novel coordination polymer [Co （C5 H5 N） 2 （ H2 O） 2 （O2 CC2 H4 CO2 ）]n was synthesized by hydrothermal reaction of COCl2 · 6H2O and butanedioic acid and trietryiamine. The structure was characterized by X-ray single crystal diffractometer and IR spectrometry. The analysis revealed the crystal belonged to the monoclinic crystal system and Pbca space group with crystallographic data as follows：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=. 528 g/cm3 ;μ=1. 101 mm-1 ;F（000） =764;R1 = 0. 0492, wR2 = 0. 0831. X-ray analysis showed that a one-dimensional interpenetrating net was formed by hydrogen bonds and π-π bonds.
