(Ethylenediamine-κ 2 N , N )bis[2-(pyridin-2-yl-κ N )-1,3-imidazol-1-ido-κ N 1 ]cobalt(III) nitrate monohydrate

In the title compound, [Co(C 8 H 6 N 3 ) 2 (C 2 H 8 N 2 )]NO 3 ·H 2 O, the Co III ion is coordinated by four N atoms from two 2-(pyridin-2-yl)-1,3-imidazol-1-ide ligands and two N atoms of ethyl­enediamine in a distorted octa­hedral geometry. In the crystal, classical N—H⋯N(O) and O—H⋯N(O) hydrogen bonds connect all the isolated components together to yield a three-dimensional structure.
