Figure 4
The inter­molecular N1—H1⋯N2 hydrogen bonds in (II)[link] (dotted lines), linking the three unique mol­ecules into a threefold helix in the [100] direction with a noncrystallographic threefold screw axis. The three unique mol­ecules A, B and C are shown, along with the adjacent triaza­penta-1,3-diene cores at either end. The view is approximately perpendicular to the bc diagonal. Ellipsoids are shown at the 30% probability level. [Symmetry codes: (i) x + 1, y, z; (iii) x − 1, y, z.]
