3-[(2,4-Di­nitro­phenyl)­hydrazono]­butan-2-one oxime

The title compound, C₁₀H₁₁N₅O₅, contains of di­nitro­phenyl, monooxime and hydrazone groups. The mol­ecules are linked through O—H...N and C—H...O hydrogen bonds. There are also π–π interactions and intramolecular hydrogen bonds. All these hydrogen bonds are highly effective in forming dimeric chains, thereby stabilizing the crystal structure. The monooxime and hydrazone groups both have an E configuration.

Special details

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
