In the title compound, C22H16N2O6, the naphthalene ring systems form a dihedral angle of 65.2 (1)°. Two O atoms of one of the nitro groups are disordered over two sets of sites with occupancy factors of 0.586 (15) and 0.414 (15). Weak C—H⋯O inter­molecular inter­actions are present, forming a ladder like structure along the a axis.

Comment top

The molecule of the title compound, C22H16N2O6, contains two naphthalene rings forming a dihedral angle of 65.2 (1)° between them. The molecular structure is shown in Fig.1. The crystal structure is stabilized by weak C17—H17···O2 intermolecular interactions forming a ladder like structure, along the a axis (Fig. 2).

Experimental top

The (S)-2,2'-dimethoxy-1,1'-binaphthalene (0.5 g,1.98 mmol) was stirred in CH3CN(10 ml). Nitric acid (0.4 ml) in glacial acetic acid (5 ml) was added dropwise in 10 minutes. The mixture was then stirred at 70°C for 16 h after pouring into the water (50 ml) and extracted with dichloromethane (3x50 ml). The organic layer was washed with 1M KOH, brine and dried over Na2SO4. The mixture was filtrated and evaporated of the solvent afforded a yellow solid,then purified by column chromatography using dichloromethane: hexane = 7:3 as an eluent. Brown crystal were obtained from a mixture of dichloromethane:hexane.

Refinement top

All H atoms of the compound were placed in calculated positions with C—H = 0.93 Å (aromatic hydrogen) and 0.96 Å (methyl hydrogen) and included in the cycles of refinement using a riding model with Uiso(H) = 1.2 Ueq(C) and Uiso(H) = 1.5 Ueq(C) ,for aromatic and methyl hydrogens respectively. The resulting Flack's parameter value was meaningless and no absolute structure could be fixed and the Fiedel's pairs were merged in the last refinement.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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.
