The solvate structure of 3,4-dichloro-1-nitrobenzene with 1,4-dioxane, C6H3Cl2NO2·0.25C4H8N2, is reported. The comprises two independent 3,4-dichloro-1-nitrobenzene molecules and half of a 1,4-dioxane molecule, the solvent molecule being disposed about a centre of inversion. Double chains of 3,4-dichloro-1-nitrobenzene are linked by Cl⋯Cl interactions and 1,4-dioxane molecules via C—H⋯O hydrogen bonds into a two-dimensional sheet.
Comment
The title compound, (I), was produced during an automated parallel crystallization polymorph screen on 3,4-dichloronitrobenzene (3,4-DCNB). The sample was identified as a novel form using multi-sample X-ray powder of all recrystallized samples (Florence et al., 2003). Subsequent manual recrystallization from a saturated 1,4-dioxane solution by slow evaporation at 298 K yielded samples suitable for single-crystal X-ray analysis. Compound (I) crystallizes in the P with two molecules of 3,4-DCNB and one half-molecule of 1,4-dioxane (disposed about a centre of inversion) in the (Fig. 1).
The is characterized by double chains of 3,4-DCNB, linked by Cl⋯Cl interactions and 1,4-dioxane molecules to give a two-dimensional sheet parallel to the (212) plane (Fig. 2). Details of the hydrogen-bonding interactions are given in Table 1. 3,4-DCNB molecules of type 2 (C7–C12) are connected to molecules of type 1 (C1–C6) via C—H⋯O hydrogen bonds and N—O⋯Cl interactions [O4⋯Cl2iv = 3.013 (1) Å and N2—O4⋯Cl2iv = 146.9 (1)°; symmetry code: (iv) 2 − x, −y, −z]. This chain is linked to another identical, but antiparallel, chain by a second set of C—H⋯O hydrogen bonds. These double chains are joined by Cl⋯Cl interactions through the type 2 molecules [Cl3⋯Cl4v = Cl4⋯Cl3v = 3.480 (1) Å and C9—Cl3⋯Cl4v = C10—Cl4⋯Cl3v = 160.3 (1)°; symmetry code: (v): 2 − x, 1 − y, −z], while the type 1 molecules are linked via the 1,4-dioxane solvent molecules by C—H⋯O hydrogen bonds, thereby forming a two-dimensional sheet. These sheets stack parallel to the (212) plane in an ABAB fashion (Fig. 3).
of (I)Experimental
A single crystal of the title compound was obtained by recrystallization from a 1,4-dioxane solution by slow evaporation at 298 K.

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. |
