Structural characterization and computational investigations of three fluorine-containing ligands with a terphenyl core

Abstract

Three linear terphenyl dicarboxylic acids with various number of fluorine addends have been prepared in a direct manner through Suzuki–Miyaura coupling. The central phenyl ring of the compounds is substituted with two or four fluorine atoms or two trifluoromethyl groups respectively. The structure and geometry of the dicarboxylic acids were confirmed by single crystal X-ray diffraction. The molecular structure of the three fluorine containing ligands was studied through molecular modeling methods. Hirshfeld surface analysis for each compound is presented.
