Comment top

The title compound, (I), was synthesized by the same method as the similar compound chlorothiazide N,N-dimethylacetamide solvate (1/2) (Johnston, Florence, Fernandes et al., 2007). Here, we report the crystal structure of (I) determined by single-crystal X-ray diffraction (Fig. 1).

The molecules of (I) crystallize in space group P1 with two chlorothiazide (CT) and two dimethyl sulfoxide (DMSO) molecules in the asymmetric unit. Bond lengths and angles in the chlorothiazide group of (I) are

comparable with those of the related compound chlorothiazide N,N-dimethylacetamide solvate (1/2) (Johnston, Florence, Fernandes et al., 2007).

Hydrogen-bonded chains of CT molecules are formed via contacts 2 and 5 (Table 1) and connected to adjacent DMSO molecules via contacts 1, 3, 4 and 6 to form a layered structure of alternating CT and DMSO molecules (Fig. 2).

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.
