1,5-Dimethyl-3-propargyl-1H-1,5-benzodiazepine-2,4(3H,5H)-dione.

ABSTRACT: The asymmetric unit of the title compound, C(14)H(14)N(2)O(2), comprises two independent mol-ecules, which slightly differ in the orientation of the propargyl chain. In both molecules, the diazepine ring adopts a boat conformation with the propargyl-bearing C atom as the prow and the C atoms at the ring junction as the stern. The carbonyl O atom of one independent mol-ecule is hydrogen bonded to the acetyl-enic H atom of the other independent mol-ecule. In the crystal, symmetry-related mol-ecules are linked together by C-H⋯O hydrogen bonds, forming a ribbon-like structure along the c axis.
