Three novel coordination networks dependent upon H2btze ligand [H2btze = 1,2-bis(tetrazol-5-yl) ethane]

Three novel metal-organic frameworks, [Zn(btze)]n (1), [Zn(btze)(H2O)]n (2) and [Mn(btze)(H2O)4]n·(H2O)2 (3) [btze = 1,2-bis(tetrazol-5-yl) ethane anion], were synthesized and characterized by elemental analysis, IR spectroscopy, X-ray crystallography and thermogravimetric analysis. The crystal structures study reveal that 1 displays a 3D framework, 2 displays a 2D layer structure and 3 displays a 1D polymeric chain. The luminescence properties of 1–3 were investigated at room temperature in solid state.
