Compound 2: the chain of rings formed by the interaction of the N12—H12⋯O11 and N19—H19⋯O4 hydrogen bonds. This chain extends along the c axis and is generated by the c-glideplane at y = . Hydrogen atoms not involved in the hydrogen bonding are omitted. Symmetry codes: (i) x, −y − , z − ; (ii) x, −y + , z + . |
