The title compound, (I) was prepared by the literature method with a minor change (Hou et al., 1968). The crystals were obtained by dissolving (I) (1.5 g, 5.7 mmole) in a mixed solvent (48 ml) (chloroform/hexane, 1:5, v/v) and evaporating the solvent slowly at room temperature for about 7 d (m.p. 383 K).
H atoms were positioned geometrically, with C—H = 0.93 and 0.96 Å for aromatic and methyl H, respectively, and constrained to ride on their parent atoms, with Uiso(H) = xUeq(C), where x = 1.2 for aromatic H and x = 1.5 for methy H atoms.
The title compound, (I), is an intermediate of pyrrole derivatives, which widely exists in alkaloids and proteins in nature (Zhu et al., 1999), and of which, acetylpyrroles have potential use for electronic transport compounds containing anthrazoline unit by a reaction with diamine compounds, according to the literature reported recently (Tonzola et al., 2003). We here report its crystal structure, which is of interest to us in the field of electronic transport materials.
In the molecule of the title compound, (I), (Fig. 1), the bond lengths and angles are within normal ranges (Allen et al., 1987). The rings A (C2—C7) and B (N/C8—C11) are, of course, and the dihedral angle between them is A/B = 101.7 (2)°.
In the crystal structure, intermolecular C—H···O hydrogen bonds (Table 1) link the molecules into chains, in which they may be effective in the stabilization of the structure.

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. |

The title compound, (I), is an intermediate of pyrrole derivatives, which widely exists in alkaloids and proteins in nature (Zhu et al., 1999), and of which, acetylpyrroles have potential use for electronic transport compounds containing anthrazoline unit by a reaction with diamine compounds, according to the literature reported recently (Tonzola et al., 2003). We here report its crystal structure, which is of interest to us in the field of electronic transport materials.
In the molecule of the title compound, (I), (Fig. 1), the bond lengths and angles are within normal ranges (Allen et al., 1987). The rings A (C2—C7) and B (N/C8—C11) are, of course, and the dihedral angle between them is A/B = 101.7 (2)°.
In the crystal structure, intermolecular C—H···O hydrogen bonds (Table 1) link the molecules into chains, in which they may be effective in the stabilization of the structure.
