Figure 1 The asymmetric unit of (I) with displacement ellipsoids for the non-hydrogen atoms drawn at the 50% probability level. The blue line on the left links the centroids of ring C1—C5 and ring C30—C35, Cg⋯Cg = 3.674 (2) Å, to emphasize their π-π-stacking interaction with C3⋯C31 = 3.300 (2) Å as the shortest corresponding distance. |
