摘要 以2,2’-联咪唑(H2biim)和邻苯二甲酸(H2phth)为配体,以钴为中心离子采用水热方法合成了配合物[Co(H2biim)2(phth)],通过单晶X-射线衍射、红外光谱、紫外光谱、热重分析和元素分析等方法对其进行了晶体结构的解析和表征。晶体属于单斜晶系,P2(1)/n空间群,晶胞参数分别为a=0.849 39(3)nm,b=1.156 45(5)nm,c=2.059 40(10)nm,β=94.769°。V=2.015 90(15)nm3,D=1.619(g/cm3),Z=4。热重分析表明,该配合物在300℃以下稳定。 The complex[Co(H2biim)2(phth)]was synthesized by hydrothermal method.It was characterized by elemental analysis,IR,UV and TG-DTA,the crystal structure was determined by X-ray diffraction.The results showed that the Co(II)complex belongs to monoclinic with space group P2(1)/n,a=0.849 39(3) nm,b=1.156 45(5) nm,c=2.059 40(10) nm,β=94.769°,V=2.015 90(15) nm3,D=1.619(g/cm3),Z=4.Thermal gravimetric analysis showed that the complex is stable below 300 ℃.
