Packing arrangements of the molecules: (a) (Ia), viewed down a [symmetry codes: (i) x, −y + , z − ; (iv) x, −y + , z + ], (b) (Ib), viewed down a [symmetry codes: (ii) −x + , y − , −z + ; (v) −x + , y + , −z + ], and (c) (Ic), viewed approximately down a. Only H atoms involved in hydrogen-bonding or N—H⋯π interactions are shown, and these interactions are indicated by dashed lines. |
