Abstract
A new metal-organic framework, {Zn[Zn3(BTA)3(μ 3-OH)(H2O)3]2}n 1, has been synthesized under hydrothermal reaction of ZnCI2 and bis(5-tetrazolyl)amine (H2BTA), and characterized by elemental analysis, FT-IR, Raman spectrum, X-ray single-crystal diffraction, TGA and photoluminescence measurements. Compound 1 crystallizes in the trigonal system, space group P-3cl, a = 13.667(3), c = 12.981(3) Å,V= 2099.6(8) Å3 and Z = 2. The BTA2- ligand in 1 assumes the μ3 tetradentate mode with both 1,2- and 1,4-tetrazole bridges, generating an unusual 2-D layer, in which the [Zn3(μ3- OH)] triangular motifs act as three-connecting nodes and the mononuclear Zn atoms as six-connecting nodes that are inter-linked by organic ligands. Adjacent 2-D metal-organic layers are linked by strong hydrogen bonds to form a novel 3-D supramolecular framework. Complex 1 exhibits blue fluorescence emission in the solid state at ambient temperature.
