Figure 2 A section of the crystal packing of the title compound, viewed along the b axis. Blue, green and red dashed lines denote the intermolecular C10—H10B⋯O1, C3—H3B⋯O2 and C7—H7A⋯O1 hydrogen bonds, respectively. Yellow and purple dashed lines denote the intermolecular C10—H10A⋯π and C4—H4A⋯π hydrogen bonds, respectively. Cg1 (black circles) is the centroid of the C1/C5—C9 ring. For symmetry operators, see Table 1. |
