Abstract

The title compound, C₁₈H₁₂N₆O₆, was prepared from the reaction of 4-(phenyldiazenyl)aniline (aniline yellow) with picrylsulfonic acid. The dihedral angle formed by the two benzene rings of the diphenyldiazenyl ring system is 6.55 (13)° and that formed by the rings of the picrate–aniline ring system is 48.76 (12)°. The molecule contains an intramolecular aniline–nitro N—H⋯O hydrogen bond.

Comment

The diazo-dye precursor aniline yellow [4-(phenyldiazenyl)aniline] reacts with strong acids to form purple-black to red-black diazenyl-protonated salts (Mahmoudkhani & Langer, 2001; Smith et al., 2009, 2011). However, our 1:1 stoichiometric reaction of aniline yellow with 2,4,6-trinitrobenzenesulfonic acid (picrylsulfonic acid) in 50% ethanol-water atypically gave orange-red crystals. This indicated a substitution reaction typical of this acid with anilines, giving N-picryl products with elimination of the sulfonate group. Reaction of picryl chloride with the isomeric aniline carboxylates to give similar products was reported by Crocker & Matthews (1911) while the application of picryl substituted azoanilines including the title compound, (I), in dyeing, was discussed by Beretta (1926). A number of structures of picryl-substituted anilines and other aromatic amines have been reported (e.g. Forlani et al., 1992; Braun et al., 2008; Pan et al., 2007; Smith et al., 2007).

In the title compound, (I), picryl-substitution of the aniline group of the 4-(phenyldiazenyl)aniline molecule has occurred. The molecular structure of (I) is shown Fig. 1. The diphenyldiazenyl ring system is non-planar [torsion angles C3—C4—N4—N41 and C51—C41—N41—N4: 175.4 (2) and -169.5 (2)°, respectively] as is the picrate to aniline ring system [torsion angles C2A—C1A—N1—C1 and C6—C1—N1—C1A: 152.5 (2) and 156.3 (3)° respectively]. Within the picrate moiety, one of the two ortho-related nitro groups is rotated out of the benzene plane [torsion angle C5A—C6A—N6A—O62A, 147.1 (2)°], while the other, which is associated with an intramolecular hydrogen bond [N1—H···O21A (Table 1)] is close to coplanar [C1A—C2A—N2A—O22A, -173.3 (2)°]. The para-related nitro group is also essentially coplanar with the ring [C3A—C4A—N4A—O42A, 172.0 (2)°]. There is one short intermolecular non-bonding nitro group interaction [O41A···O42Aⁱ, 2.860 (3) Å: symmetry code (i) -x + 1, y - 1/2, -z]. In addition, there are weak π···π ring interactions with a centroid to centroid distance 3.7744 (16) Å.

Experimental

The title compound was synthesized by heating together under reflux for 10 minutes, 1 mmol quantities of 4-(phenyldiazenyl)aniline (aniline yellow) and 2,4,6-trinitrobenzenesulfonic acid (picrylsulfonic acid) in 50 ml of 50% ethanol-water. After concentration to ca 30 ml, partial room temperature evaporation of the hot-filtered solution gave orange-red prisms of (I) from which a specimen was cleaved for the X-ray analysis.

Special details

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

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.
