Three new copper complexes and one cobalt complex with 5-(pyrazinyl)tetrazolate anion, (pyztz)(-), as chelating bidentate ligand, were obtained by the reaction of pyrazinecarbonitrile with sodium azide in the presence of copper(II) nitrate or cobalt(II)chloride. Complexes of composition [Cu(pyztz)(2)(H2O)] (1) deep blue crystals, [Cu(pyztz)(2)(H2O)(2)] (2a) green crystals, [Co(pyztz)(2)(H2O)(2)] (2b)
