Figure 3
Part of the crystal structure of (I

), showing the C—H⋯π interactions linking the hydrogen-bonded chains into a three-dimensional framework. The C12—H12B, C6—H61 and C7—H7 bonds point towards atom N9ⁱⁱ, atom C1ⁱⁱⁱ and the C4—C10ⁱⁱⁱ bond, respectively. C—H⋯π interactions are indicated by dotted lines and the unit-cell box has been omitted for clarity. [Symmetry codes: (ii) 2 − x, y − $[{1\over 2}]$ , $[{3\over 2}]$ − z; (iii) $[{1\over 2}]$ + x, − $[{1\over 2}]$ − y, 1 − z.]
