Abstract

The seven-membered ring in the title compound, C(15)H(12)N(2)O, adopts a boat-shaped conformation (with the methyl-ene C atom as the prow and the double-bond C=N pair of atoms as the stern). In the crystal, adjacent mol-ecules are linked by an N-H⋯O hydrogen bond to generate helical chains running along the a axis of the ortho-rhom-bic unit cell.
