Bis(ethylenediamine-κ2N,N′)(nitrato-κ2O,O′)cobalt(III) hydroxide nitrate

The Co ion in the title salt, [Co(NO3)(H2NCH2CH2NH2)2](OH)(NO3), has oxidation state + III and is coordinated by four N atoms from two ethylenediamine molecules and two O atoms from a nitrate anion in a distorted octahedral geometry. The charge of the complex cation is balanced by a hydroxide anion and a nitrate anion. The cations and anions are connected by N—H...O and O—H...O hydrogen bonds, resulting in a three-dimensional supramolecular framework. There are two independent ion pairs with similar configurations in the unit cell. Both uncoordinated nitrate counter-anions are disordered
