by Secondo, P. M.; Hester, C. A.; Collier, H. L.; Baughman, R. G.; Cordes, A. W.

A crystallographic twofold rotation axis passes through the C-C bond joining the imidazole rings of the title compound, C10H10N4O2. The molecule crystallizes in a cis disposition. The planar acetyl group is twisted by 5.0(3)degrees with respect to the imidazole ring and the two imidazole rings are tilted by 60.53(5)degrees in relation to one another.
