Abstract:

Hydrothermal reaction of 5,5'-dicyano-3,3'-bipyridyl ligands and sodium azide in the presence of the Lewis acid CuSO4 in water and ethanol provided a novel metal organic tetrazole complex. X-ray single crystal diffraction analysis shows that this complex belongs to a tetragonal system with P4/ncc space group. This complex displays an interesting infinite two-dimensional(2D) network structure bridge linked by the pyridyl N atoms. The highly disordered sulfate around the central metals are likely to become ordered at low temperatures, leading to structural phase changes. The packing diagram of the crystal structure shows a butterfly hairpin shape. The highly nitrogenated structure allows this complex to be a potential high-energy material.

Key words: tetrazole complex, pyridyl, two-dimensional network structure
