Figure 2
A partial view of the crystal packing of (I), showing the formation of an N—H⋯N hydrogen-bonded tetramer. Hydrogen bonds are shown as dashed lines and atoms labelled a, b and c correspond to symmetry operations (y, − x, − z), ( − x, − y, z) and ( − y, x, − z), respectively. H atoms not involved in hydrogen bonds have been omitted. |
