Abstract

There are two geometrically different mol-ecules in the asymmetric unit of the title compound, C(14)H(9)Cl(2)NO(3). The 5-amino-2-hy-droxy-benzoic acid units [r.m.s. deviations of 0.0323 and 0.0414 Å] and 2,6-dichloro-benzaldehyde groups [r.m.s. deviations of 0.0285 and 0.0226 Å] are roughly planar and oriented at dihedral angles of 11.69 (13) and 83.12 (6)° in the two mol-ecules. An intra-molecular O-H⋯O hydrogen bond completes an S(6) ring motif in each mol-ecule. The two mol-ecules form dimers with each other through inter-molecular O-H⋯N and C-H⋯O hydrogen bonds, completing an R(2) (2)(8) ring motif. The dimers are inter-linked via inter-molecular O-H⋯N and C-H⋯O hydrogen bonds, forming polymeric sheets.

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles
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.
