Abstract

An X-ray crystallographic study of 2,5-dimethyl-3,4-diacetylpyrrole showed that the crystals are monoclinic, space group P21/n, a = 10·01(3), b = 12·93(3), c = 7·41(2) Å and β = 91·5(5) °. The crystal structure was solved by direct methods and refined by least squares to a final R factor of 0·13. The values determined for the bond distances and angles of the pyrrole ring are in good agreement with the values reported in the literature. However, there are significant changes in the exocyclic bond angles of the atoms of the ring. The planes of the acetyl groups are tilted with respect to the ring plane, forming dihedral angles of 22 ° and 40 °.
