The interaction of 1‐phenyl‐1,4‐dihydro‐5 H ‐tetrazol‐5‐one (Hpto) with ethylenediamine (en) and metallic copper in ethanol in the open air was found to yield molecular complexes [Cu(en) 2 (pto) 2 ] ( 1 ) or [Cu 2 (en) 2 (EtOH) 2 (pto) 4 ] ( 2 ) depending on the reagents ratio. Deprotonated tetrazol‐5‐one, i.e 1‐phenyltetrazol‐5‐olate anion (pto) acts as a monodentate ligand coordinated to the metal via the tetrazole ring N 4 atom in mononuclear complex 1 , and as a bridging ligand coordinated via the tetrazole ring N 4 and N 3 atoms in binuclear complex 2 . The latter was found to be a paramagnet, with a very weak antiferromagnetic exchange interaction between copper ions.
