10,11-Dihydrocarbamazepine (form III)

Abstract

The title compound (systematic name: 10,11-dihydro-5H-dibenz[b,f]azepine-5-carboxamide), C15H14N2O, is shown to crystallize as a triclinic polymorph with Z′ = 2. N—H⋯O and N—H⋯π inter­actions combine to create a catemeric motif. The robustness of this motif is reflected in the fact that it is also observed in the previously published monoclinic and ortho­rhom­bic forms of the compound.
