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。

Using phenanthroline （phen） as an auxiliary azide-bridging ligand, a Co2＋ coordination polymer [Co2（μ1,1-N3）2（phen）2（N3）2], was prepared hydrothermally. The complex was characterized by IR, elemental analysis, X-ray single crystal diffraction. The bridging manner of azide in this complex was discussed and the magnetic properties were measured. The complex belongs to the triclinic system （space group of P1） with 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.
