In the distorted octahedral title complex, [Co(NO2)-(C2H6O)(C4H7N2O2)(2)],
the Co atom is coordinated to two chelating ligands in the equatorial plane
, with nitro and ethanol groups occupying the axial positions. In addition
to the asymmetric intramolecular hydrogen bridges between the equatorial li
gands, strong intermolecular hydrogen bonds result in a pairwise arrangemen
t of the molecules with respect to a crystallographic inversion center.
