Packing diagram illustrating centroid-stacking interactions down the b-axis direction (a) between parallel-aligned ring systems with co-planar molecules flipped across an inversion centre [centroid-to-centroid distance = 3.712 (6) Å] and packed back to back [centroid-to-centroid distance = 3.717 (6) Å]. The three molecules are staggered with an angle of 166.698 (17)° and two molecules fit within the the P unit cell. |
