用水热法合成了以邻菲啰啉(phen)为辅助配体叠氮桥联Co2+配位聚合物:[Co2(μ1,1-N3)2(phen)2(N3)2]。用IR和元素分析进行了表征,用单晶XRD测定晶体结构,属于三斜晶系,P1空间群,a=0.69272(14)nm,b=1.0318(2)nm,c=1.0381(2)nm,α=6.447(3)°,β=71.02(3)°,γ=85.79(3)°,Z=1,V=0.6312(2)nm3,D=1.701 mg/mm3,F(000)=326。确定N3-为μ-1,1桥联配位。测定了配合物固体的变温磁化率,证明配合物为亚铁磁性物质,其临界温度为15 K。
Hydrothermal synthesis of azodicarbonamide bridged Co2 + coordination polymer with phenanthroline (phen) as auxiliary ligand: [Co2 (μ1,1-N3) 2 (phen) 2 (N3) 2] The crystal structure was characterized by IR and elemental analysis. The crystal structure was determined by single crystal XRD and belongs to the triclinic system with a = 0.69272 (14) nm, b = 1.0318 (2) nm and c = 1.0381 , α = 6.447 (3) °, β = 71.02 (3) °, γ = 85.79 (3) °, Z = 1, V = 0.6312 (2) nm3, D = 1.701 mg / . It is determined that N3 - is the μ-1, 1 bridging coordinate. The temperature-dependent magnetic susceptibility of the complex was determined. The results show that the complex is ferrimagnetic with a critical temperature of 15 K.
