Crystal structure of (1E,1′E)-1,1′-(pyridine-2,6-diyl)bis[N-(2,3,4,5,6-pentafluorophenyl)ethan-1-imine]

Abstract

The title compound, C21H9F10N3, represents a potential redox non-innocent pyridine diimine ligand system. It consists of a central pyridine ring with two pentafluorophenyl substituted imine groups in positions 2 and 6. The whole molecule is generated by mirror symmetry, the mirror bisecting the N and para-C atom of the pyridine ring. The perfluorophenyl ring is inclined to the pyridine ring by 73.67 (8)°. In the crystal, molecules stack along the a axis, but there are no significant intermolecular interactions present.
