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⋯O bonds and N—H⋯π inter­actions in both crystal modifications. The two polymorphs appear to form due to different van der Waals inter­actions between the layer-like sheets of mol­ecules.
