Abstract

In the title compound, C15H12N2O, the phenyl ring makes a dihedral angle of 32.45 (9)degrees with the benzene ring of the 1,5-benzodiazepin-2-one unit. The seven-membered ring adopts a boat conformation with the methylene group as the prow and the fused benzene-ring C atoms as the stern. In the crystal, inversion dimers linked by pairs of N-H center dot center dot center dot O hydrogen bonds generate R-2(2)(8) loops. The dimers are further linked by CH center dot center dot center dot O hydrogen bonds, so forming a column along the a-axis direction.
