Luminescent zinc and cadmium metal-organic frameworks based on tetrazole ligands

Three metal-organic frameworks with 1D zigzag chain [Zn(dte)(H2O)3]·2H2O (1), 2D double layer [Cd(dtb)(H2O)(phen)] (2), 3D network [Zn(dte)(phen)] (3) based on tetrazole-based ligands (H2dtb = 1,3-dis(2H-tetrazol-5-yl)benzene, H2dte = 1,4-ditetrazolylethylene, phen = 1,10-phenanthroline), have been synthesized and characterized. All the compounds exhibit unusual strong luminescence at room temperature in the solid state and can be potentially used as luminescent materials.
