Figure 3
Selected intermolecular interactions in the crystals of (a) the monoclinic form and (b) the triclinic form. Purple dashed lines represent the C—H⋯O hydrogen bonds and green dashed lines the C—H⋯π and π–π interactions. Cg1 is the centroid of the C5–C10 ring, while Cg2 is the midpoint of the C12≡C13 bond. |
