3,8-Dimethyl-quinazoline-2,4(1H,3H)-dione.


ABSTRACT: In the title compound, C(10)H(10)N(2)O(2), all non-H atoms are approximately co-planar with an r.m.s. deviation of 0.016?Å. In the crystal, mol-ecules are linked into inversion dimers by pairs of N-H?O hydrogen bonds. Chains along [010] are buiilt up by ?-? inter-actions [centroid-centroid distance = 3.602?(1)?Å] between the benzene and piperazine rings of adjacent mol-ecules.

In the title compound, C(10)H(10)N(2)O(2), all non-H atoms are approximately co-planar with an r.m.s. deviation of 0.016 Å. In the crystal, mol-ecules are linked into inversion dimers by pairs of N-H⋯O hydrogen bonds. Chains along [010] are buiilt up by π-π inter-actions [centroid-centroid distance = 3.602 (1) Å] between the benzene and piperazine rings of adjacent mol-ecules. ...[more]
