Synthesis and structure of 4-[(2,3,4,5,6-penta­fluoro­phen­­oxy)carbon­yl]phenyl 4-(dodec­yl­oxy)benzoate

Abstract

In the title compound, C32H33F5O5, the dihedral angle between the central carbonyl­pheyl and peripheral perfluoro­phen­oxy and (dodec­yloxy)benzoate rings are 85.24 (2) and 78.98 (2)ο, respectively, indicating that the central ring is almost normal to both adjacent rings. The pendant C12 alkyl chain adopts an all-anti conformation. In the crystal, weak C—H⋯O hydrogen bonds connect the mol­ecules, forming S(7) chains propagating along the [010] direction. The packing is consolidated by C—F⋯π inter­actions and weak π–π stacking. The Hirshfeld surface analysis reveals that the major contributions to the two-dimensional fingerprint plots are from H⋯H (45%),F⋯H/H⋯F (18.5%), O⋯H/H⋯O (9.7%), C⋯H/H⋯C (9.4%), F⋯C/C⋯F (7.3%), and F⋯F (1.9%) contacts. An energy framework calculation shows that dispersion energy (–383.4 kJ mol−1) makes by far the largest contribution.
