Figure 4
Compound (4: R = C₆H₅). (a) Part of a one-molecule-wide column formed from linking molecules by a combination of C4—H4⋯O31, and C5—H5⋯O31, C34—H34⋯O2 and C346—H346⋯O1 hydrogen bonds. Within these columns are R₂¹(5), R₂²(10) and R₂²(16) rings and (b) part of a column formed from two alternating π–πⁱ and π–πⁱⁱ interactions [symmetry codes: (i) 1 − x, −y, 1 − z; (ii) 1 − x, 1 − y, 1 − z].
