Abstract

A new Zn(II) metal–organic framework, namely [Zn3(3-atrz)2(4-atrz)2(SO4)2]n (1 3-atrz = 3-amino-1,2,4-triazole, 4-atrz = 4-amino-1,2,4-triazole), has been solvothermally synthesized via the reactions of ZnSO4·7H2O and two different kinds of isomorphic aminotriazole ligands (3-atrz and 4-atrz). Single crystal X-ray diffraction analysis revealed that compound 1 features a trinuclear [Zn3(3-atrz)2(4-atrz)2(SO4)2] subunits based 3D framework with 6-connected pcu topology. In the 3D framework of 1, 3-atrz ligand displays a μ3-κN1, κN2, κN3 coordination mode and 4-atrz ligand displays a μ2-κN1, κN2 coordination mode. The luminescent properties investigation indicated that compound 1 shows strong luminescence at room temperature and high selectivity and sensitivity for Fe3+ ion in aqueous solution.
