Comment top

A few crystal structures containing 2-methyl-5-nitrobenzenesulfonate have been reported previously (Gu et al., 2007; Xie et al., 2007; Xie, Lui & Yuan, 2006; Xie, Yang et al., 2006).

In the asymmetric unit of the title compound, the 2-ethanolamine molecule is protonated and the 2-methyl-5-nitrobenzenesulfonic acid molecule loses its acid H atom, then they are linked by an N2—H2B···O5 hydrogen bond (Fig. 1 & Table 1). The plane of nitro group is skew with the plane of benzene ring in a dihedral angle of 17.5 (2)°. The C1—C2 bond [1.4054 (16) Å] is the longest one among the other aromatic C—C bond, this is consistent with the situations observed in the previous cases (1.405 Å, Gu et al., 2007; 1.404 Å, Xie, Lui & Yuan, 2006; 1.407 Å, Xie et al., 2007; 1.408 Å, Xie, Yang et al., 2006).

A few crystal structures containing 2-methyl-5-nitrobenzenesulfonate have been reported previously, they are pyridinium derivative (Gu et al., 2007), nickel (Xie, Yang et al., 2006), magnesium (Xie et al., 2007), and potassium salts (Xie, Lui & Yuan, 2006). In the potassium salt, all of the oxygen atoms of sulfonate and one oxygen atom of the nitro group is coordinated with potassium atom directly. However, there exists no covalent bond between the counter ion pair in the title compound, which is similar with the other three previous cases. In all of these cases, one of C-C bond of benzene rings are slightly abormal.

In the crystal, the 2-hydroxyethanaminium cations and the MNB anions are linked by N—H···O and O—H···O hydrogen bonds (Table 1) to form thick layers (Fig. 2) parallel to the (100) plane. The nearest separation between the centroid of MNB benzene rings is of 4.483 (3) Å, suggesting no ππ interaction. This situation is similar to that observed in the case containing a large sized organic cation as counter ion for MNB anion (Gu et al., 2007), but is different from those observed in other cases containing metal cations as counter ion for MNB anion (Xie et al., 2007; Xie, Lui & Yuan, 2006; Xie, Yang et al., 2006).

Experimental top

2-Methyl-5-nitrobenzenesulfonic acid (12.1 g) and 2-ethanolamine (5.0 g) were mixed and dissolved in sufficient water (25 ml) by heating to 373 K, at which point a clear solution resulted. The solution was then cooled slowly to room temperature. Crystals of the title compound (9.2 g) were formed upon the evaporation of water, then collected and washed with ethanol.

Refinement top

All H atoms of hydroxyl and ammonium groups were located in a difference Fourier map. The H atoms of ammonium group were refined freely, but the H atom of hydroxyl group was refined with a distance restraint O—H = 0.82 (1) Å, and with Uiso(H) = 1.5Ueq(O). Other H atoms were placed in calculated positions (C—H = 0.93–0.97 Å) and allowed to ride on their parent atoms, with Uiso(H) = 1.2Ueq(C).

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.
