摘　　要：本文合成了一个新的配位聚合物{[Co_(0.5)(C_5H_5N)(C_6H_5N_2O_2)·2H_2O]·3H_2O}_n,并测定了其晶体结构。该晶体属于正交晶系,Fdd2空间群,晶胞参数:a=22.2942(16)?,b=20.8430(14)?,c=13.8157(8)?,α=90o,β=90o,γ=90o,V=6419.8(7)?~3,Z=16,Dc=1.390 mg/m^3,最终偏差因子R_1=0.0596,wR_2=0.1633[I>2σ(I)],F(000)=2824.0。该配合物通过分子间氢键作用形成三维网络结构。A new coordinate polymer {[Co0.5（C5H5N）（C6HsN202）·2H2OI·3H20}, is synthesized and characterized structurally by single crystal X-ray diffraction. The complex crystallizes in triclinic system, space group P-lwith a=22.2942（16）A,b=20.8430（14）A,c=13.8157（8）A,a=90°β=900,Y=90°,V=6419.98（7）A3,Z=16,Dc==1.390mg/m3. The final R value is RI= 0.0596, wR= 0.1633 [1〉2o（1）], F（000）=2824.0. The packing of the molecules is mainly a result of hydrogen bonds resulting in a three-dimensional structure.
