The title compound, C12H18N4O6S (systematic name: 4-di­propyl­amino-3,5-di­nitro­benzene­sulfonamide), is a sulfonamide with herbicidal properties marketed as oryzalin. The dihedral angles between the benzene ring and the mean planes of the nitro groups are 26.15 (11) and 54.80 (9)°. The propyl arms of the di­propyl­amino substituent lie on opposite sides of this ring plane. In the crystal, N—H⋯O and C—H⋯O hydrogen bonds generate a three-dimensional network.

Supporting information


Comment top

Oryzalin, C12H18N4O6S, is a sulfonamide herbicide for soybean and crop weeds (Naqvi & Leung, 1983). Its crystal structure is reported herein. In this compound (Scheme 1, Fig. 1), the dihedral angles between the central phenyl ring and the mean planes of two nitro groups are 26.15 (11) and 54.80 (9)°, respectively. All bond lengths and bond angles are normal and comparable to those observed in the crystal structures of similar compounds (O'Connell & Maslen, 1967; Tremayne et al., 2002).

In the crystal structure (Fig. 2), the crystal structure is stabilized by intermolecular N—H···O and C—H···O hydrogen bonds (Table 1), resulting in a three-dimensional architechture.

Experimental top

The title compound was purchased from the Dr. Ehrenstorfer GmbH Company. Slow evaporation of a solution in CH2Cl2 gave single crystals suitable for X-ray analysis.

Refinement top

The N-bound H atoms were located in a difference Fourier map and freely refined (N—H = 0.81 (2) - 0.86 (2) Å). The C-bound H atoms were positioned geometrically and refined using a riding model with d(C—H) = 0.98 Å, Uiso = 1.2Ueq(C) for methyl group, d(C—H) = 0.99 Å, Uiso = 1.2Ueq(C) for Csp3—H, and d(C—H) = 0.95 Å, Uiso = 1.2Ueq(C) for aromatic C—H.

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.
