Bis(ethylenediamine-²N,N')(nitrato-²O,O')cobalt(III) hydroxide nitrate

J.-B. Zhang and X.-S. Qu

Abstract: 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-HO and O-HO 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.
