Crystal packing analysis of in situ cryocrystallized 2,2,2-tri­fluoro­aceto­phenone

Crystals of the liquid compound 2,2,2-tri­fluoro­aceto­phenone (TFAP, C(8)H(5)F(3)O) were obtained using the state-of-art in situ cryocrystallization technique. TFAP crystallizes in the monoclinic space group C2/c, and its crystal structure is mainly stabilized by a set of C—H⋯F, C—H⋯O, F⋯F and F⋯O supra­molecular contacts. The overall mol­ecular arrangement shows the formation of mol­ecular sheets parallel to the bc plane, which are in turn stacked along the a-axis direction. The weak inter­actions have been studied thoroughly, performing both a Hirshfeld surface analysis and theoretical calculations, to obtain the inter­molecular inter­action energies. A structural comparison of this compound with the previously reported substituted analogs was also carried out, showing a qualitative difference in terms of packing behaviour.
