采用溶液热合成方法, 得到了新颖的Co(Ⅱ)配位聚合物单晶体. 它是以[Co2(C3H4N2)4(C10H2O8)]为重复单元、用均苯四甲酸根为桥而联成的一维无限链状聚合物. 该配合物单晶属三斜晶系, 空间群P1, a = 0.9610(1) nm, b = 0.9684(1) nm, c = 0.7924(1) nm, a = 96.695(9)? b = 102.741(6)? g = 116.551(5)? V = 0.6236(2) nm3, Z = 2, R1 = 0.0342, wR2 = 0.0990. 表面光电压光谱测试结果表明, 它在300~800 nm范围内, 表现出了较明显的光伏响应带. 另外从该化合物的变温磁化率研究结果可以看出, 该聚合物具有弱的反铁磁物质行为.
A novel single crystal of Co (Ⅱ) coordination polymer was obtained by the solution thermal synthesis method. It is a complex of [Co2 (C3H4N2) 4 (C10H2O8)] with pyromellitic acid as the bridge The complex is a monoclinic triclinic with space group P1, a = 0.9610 (1) nm, b = 0.9684 (1) nm, c = 0.7924 (1) nm, a = 96.695 (2) nm3, Z = 2, R1 = 0.0342, wR2 = 0.0990. The results of surface photovoltage spectroscopy show that it is in the range of 300-800 nm , A more obvious band of PV response is shown.In addition, the results show that the polymer has a weak antiferromagnetic behavior.
