Crystal structure of (E)-9-(4-nitro-benzyl-idene)-8,9-di-hydro-pyrido[2,3-d]pyrrolo-[1,2-a]pyrimidin-5(7H)-one.


ABSTRACT: The title compound, C17H12N4O3, a pyrido-pyrrolo-pyrimidine derivative, is almost planar. The nitro-benzene ring is inclined to the mean plane of the 8,9-di-hydro-pyrido[2,3-d]pyrrolo-[1,2-a]pyrimidin-5(7H)-one moiety (r.m.s. deviation = 0.023?Å) by 6.8?(1)°. In the crystal, mol-ecules are linked via C-H?O and C-H?N hydrogen bonds, forming layers parallel to (101).
