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
