Views of the N—H⋯N and C—H⋯π inter­actions (dotted lines) in the crystal structures of (I)[link] and (II)[link]. H atoms not participating in hydrogen bonding have been omitted for clarity. The largest spheres indicate the centroids of the C7–C12 rings (Cg1). (a) The structure of (I)[link] with the H atom on N1, (b) the structure of (I)[link] with the H atom on N2 and (c) the structure of (II)[link]. [Symmetry codes: (i) −x + [{1\over 2}], −y + [{3\over 2}], −z + 1; (ii) −x + 1, −y, −z.]
