Abstract

In the title compound, C(24)H(18)N(2)O(4)·CHCl(3), the phenyl and benzene rings make a dihedral angle of 38.60 (9)° and connect in an orientation almost perpendicular to the naphthalene ring system at dihedral angles of 78.73 (8) and 81.20 (7)°. The mol-ecule has a Z configuration about the C=N bond. In the crystal, mol-ecules are linked by inter-molecular O-H⋯N=C hydrogen bonds between the imino moiety and hy-droxy groups. Inter-molecular C-Cl⋯C inter-actions between Cl atoms of the CHCl(3) mol-ecule and C atoms of the naphthalene rings are also present [Cl⋯C = 3.353 (2) and 3.326 (19) Å]. The nitro group and the chloro-form solvent mol-ecule are disordered over two positions with site occupancies of 0.884 (4) and 0.116 (4).

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.
