The asymmetric unit of the title compound, C15H14ClN3O6, contains two independent mol­ecules. The imidazole rings are oriented with respect to the benzene rings at dihedral angles of 19.66 (3) and 21.64 (3)°. In the crystal structure, inter­molecular O—H⋯N hydrogen bonds link the mol­ecules into infinite chains.

Comment top

As part of our ongoing studies, we synthesized the title compound, (I), and report herein its crystal structure.

The asymmetric unit of the title compound, (I), contains two independent molecules (Fig. 1), in which the bond lengths are within normal ranges (Allen et al., 1987).

Rings A (C1–C6), B (N1/N2/C13–C15), C (C17–C22) and D (N4/N5/C29–C31) are, of course, planar and the dihedral angles between them are A/B = 19.66 (3)° and C/D = 21.64 (3)°.

In the crystal structure, intermolecular O—H···N hydrogen bonds (Table 1) link the molecules into infinite chains (Fig. 2), in which they may be effective in the stabilization of the structure.

Experimental top

For the preparation of the title conpound, ornidazole (14.6 g, 66 mmol), phthalic anhydride (11.8 g, 80 mmol), acetone (80 ml) and pyridine (6 ml) were added into a three-necked round-bottom flask (250 ml) fitted with a mechanical stirrer and a reflux condensing tube. The mixture was stirred until the solids were completely dissolved, and heated to reflux for about 7 h, and then the reaction was stopped and the mixture was cooled. After filtration of the mixture under vacuum, the colorless deposition was obtained (yield; 18 g, 74%). Suitable crystals for X-ray analysis were obtained by dissolving the title compound (0.1 g) in dry methanol (5 ml), and then allowing the solution to evaporate slowly at room temperature for about 12 d.

Refinement top

H atoms were positioned geometrically, with O00—H = 0.82 Å (for OH), C-00H = 0.93, 0.98, 0.97 and 0.96 Å for aromatic, methine, methylene and methyl H, and constrained to ride on their parent atoms, with Uiso(H) = xUeq(C,O), where x = 1.5 for OH and methyl H, and x = 1.2 for all other H atoms.

Special details top

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.
