Crystal Structure of the 4-Cyanophenyl 4-Perfluorohexylbenzoate

Abstract

The title compound crystallizes with four molecules in the asymmetric unit. They adopt a slightly bent conformation with quite extended perfluorinated aliphatic chain. The molecular arrangement is characterized by the segregation of the cores 4-cyanophenyl 4-benzoate on one side and the perfluorinated aliphatic chains on the other side. The molecules give bilayer sheets, parallel to the xoy plane, the thickness of bilayers being equal to the c parameter. The interactions between the sheets are quite weak.
