In the title compound, [Co(C12H12N2)2(N3)2]·H2O, the Co(II) ion is situated on a crystallographic twofold axis and adopts a distorted octahedral geometry with the two dmbpy (dmbpy = 5,5′-dimethyl-2,2′-bipyridyl) and the two azido ligands in a cis arrangement. The solvent water molecule and one methyl group of the dmbpy ligand are disordered over two sets of sites in a 1:1 ratio. The crystal structure is stabilized by intramolecular C—H⋯N(dmbpy) and intermolecular O—H⋯N(azide) hydrogen bonds.
