Crystal structure of (1Z,4Z)-2,4-dimethyl-3H-benzo[b][1,4]diazepine

The title compound, C11H12N2, is not planar due to the folding of the seven-membered ring. In the crystal, molecules are packed opposite each other to minimize the electronic repulsion but the long intermolecular distances indicate that no directional contacts are found.Funding for this research was provided by: Ministerio de Economía y Competitividad, Secretaría de Estado de Investigación , Desarrollo e Innovación (award No. CTQ2014- 56933-R); Ministerio de Economı´a y Competitividad, Consejo Superior de Investigaciones Cientı´ficas (award No. CTQ2015- 63997-C2-2-P); Comunidad Autónoma de Madrid (award No. S2009/PPQ-1533); Universidad Nacional de Educación a Distancia (award No. GI_SUPRABIO_01).Peer Reviewe
