4-Chloro-2-[(E)-({4-[N-(3,4-dimethyl-isoxazol-5-yl)sulfamo-yl]phen-yl}iminio)meth-yl]phenolate.

The title compound, C(18)H(16)ClN(3)O(4)S, is a Schiff base ligand in which the H atom of the hydr-oxy group has moved to the N atom of the imine group, resulting in a zwitterion. The structure is stabilized by an intra-molecular (N-H⋯O) and five inter-molecular (C-H⋯O, C-H⋯N and N-H⋯O) hydrogen bonds. The mol-ecules are linked to each other by hydrogen bonds and form a three-dimensional polymeric network. In addition, the aromatic rings are also involved in π-π inter-actions [centroid-centroid distance between aromatic rings = 3.7525 (11) Å].

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.
