Table 6. stacking (, ).

Cg1, Cg2, Cg3 and Cg7 [compound (6)] are the centroids of the rings containing atoms O1, C5, C311 and C211 [compound (6)], respectively. In contacts indicated *, the planes involved are inclined to each other, the perpendicular distance between the planes is an average value and the angle between the planes is given in place of a slippage. Only interplanar interactions with Cg Cg distances 4.0 and with angles between the planes of 10 are included.
