Packing diagram of (III)[link], displaying the N—H⋯Br hydrogen bonding and the head-to-tail stacking between inversion-center-related mol­ecules. Only the H atoms involved in hydrogen bonding and the major contributor to the disorder model are shown. [Symmetry codes: (i) −x, −y + 2, −z; (ii) −x, −y + 1, −z; (iii) x, y − 1, z; (iv) x, y − 2, z + 1; (v) −x, −y + 1, −z + 1; (vi) x, y, z + 1; (vii) −x, −y + 2, −z + 1.]
