Solvothermal reactions of 4‐cyanopyridine N ‐oxide, NaN 3 , and hydrated M Cl 2 ( M = Cu, Co) in a mixture of EtOH/H 2 O afford the 3D polymer [Cu I (4‐ptz)] n ( 1 ) and the mononuclear complex [Co II (4‐ptz) 2 (H 2 O) 4 ] ( 2 ) (4‐ptz = 5‐(4‐pyridine N ‐oxide) tetrazolate). The crystal structures of both compounds were determined by X‐ray crystallography, in which the ligand 4‐ptz exhibited different coordination modes. The thermal stability of 1 was measured by thermogravimetric analysis (TGA) and the solid state luminescence property of 1 was investigated at room temperature.
