✦ Synopsis

A new copper(II) tetrazolate coordination polymer [Cu(pzta) 2 ] n (1) (pzta＝5-pyrazinyltetrazolate) was prepared from the hydrothermal reaction of Cu(OAc) 2 •H 2 O with NaN 3 and pyrazinecarbonitrile (pzCN) in the presence of ethanol, and characterized by elemental analysis, IR, TGA and X-ray crystallography. The X-ray diffraction analysis of 1 shows that the compound crystallizes in the monoclinic system with space group P2(1)/c and Cu(II) ion center is six-coordinated by four different pzta ligands. The complex 1 features a 2D tetrazole coordination polymer. The thermal analysis of 1 shows that the decomposition of the complex occurs in two regions.
