摘要:

以5-叠氮间苯二甲酸(H2aip)为有机酸配体, 选择3种不同的含氮辅配体, 在溶剂热条件下合成了4个配位聚合物: Co(aip)(py)3(1), Co(aip)(4,4'-bipy)(2), Mn(aip)(4,4'-bipy)(3)和Mn(aip)(dptz)(4)[py=吡啶, 4,4'-bipy=4,4'-联吡啶, dptz=3,6-二(4-吡啶基)-1,2,4,5-四嗪], 通过X射线单晶衍射确定了化合物的晶体结构, 并通过元素分析、 红外光谱、 热重和粉末X射线衍射对化合物进行了表征. 结构分析表明, 化合物1属单斜晶系, C2/c空间群, 具有一维链状结构; 化合物2和3结构相同, 均属单斜晶系, C2/m空间群, 具有二维层状结构, 化合物4属三斜晶系, P1ˉ空间群, 具有二维层状结构. 变温磁化率测试结果表明, 所得4个化合物中均存在弱反铁磁作用.

Abstract:

Four coordination polymers, Co(aip)(py)3(1), Co(aip)(4,4'-bipy)(2), Mn(aip)(4,4'-bipy)(3) and Mn(aip)(dptz)(4)[Py: pyridine; 4,4'-bipy: 4,4'-dipyridyl; dptz: 3,6-bis(4-pyridyl)-1,2,4,5-tetrazine] were synthesized by the reaction of 5-azidoisophthalic acid(H2aip) and auxiliary ligands with transition metal. The structures of the complexes were characterized by single crystal X-ray diffraction, powder X-ray diffraction, elemental analyses, infrared spectroscopy and thermal-gravimetric analysis. The structural analyses of compound 1 show that the complex belongs to the monoclinic system, and the space group is C2/c with a 1D chain structure. Compounds 2 and 3 belong to the monoclinic system, and the space group is C2/m with 2D network structures. For compound 4, the space group is P1¯ with a 2D network. The magnetic properties were also characterized. The results reveal that anti-ferromagnetic interaction exists in compounds 1—4.

Key words: Crystal structure, Solvothermal synthesis, Coordination polymer, Magnetic property, 5-Azidoisophthalic acid ligand
