Abstract

The title compound (systematic name: 10,11-dihydro-5H-dibenz[b,f]azepine-5-carboxamide), C15H14N2O, is shown to crystallize as an orthorhombic polymorph to complement the known monoclinic form. The molecular conformations of both forms are very similar, involving a bent conformation for the seven-membered azepine ring and an overall `butterfly' shape. The molecules assemble into chains by way of N-H center dot center dot center dot O bonds and N-H center dot center dot center dot pi inter-actions in both crystal modifications. The two polymorphs appear to form due to different van der Waals inter-actions between the layer-like sheets of molecules.
