摘要
A novel Cu (II)-MOF, namely [Cu(Hhmt)](n) (1) was obtained by employing copper nitrate and a triazole ligand (H(3)hmt) under hydrothermal conditions, where H(3)hmt = 3,5-bis (hydroxymethyl)-1,2,4-triazole. Single crystal X-ray analysis reveals that complex 1 crystallizes in the chiral tetragonal space group P4(3)2(1)2 with a right-handed 4(3) and a left-handed 2(1) helical chains which lead to the formation of a 3D supramolecular structure. The phrase purity, IR spectra, thermal stabilities of 1 were also investigated. The nature of antiferromagnetic exchange of complex 1 is discussed based on the structure.
