2,2′,6,6′-Tetramethyl-4,4′-bipyridine

Abstract

In the title compound, C14H16N2, which has no crystallographic molecular symmetry, the dihedral angle between the least-squares planes of the two pyridine rings is 19.48 (2)°. No classical hydrogen bonds nor π–π inter­actions were found.

“…1b). In contrast, the molecule exhibits a twisted conformation in the crystal structure of the unsolvated free ligand, with a dihedral angle between the mean planes of the rings of 19.48 (2) (Fu, 2008). The molecule is also found to be twisted in Fujita's coordination cages (see above).…”
