    • 2ν symmetry with a planar conformation in the complexes and a box shape for 1 was pointed out by one of the referees. PM6 calculations suggested that benzophenone with a planar conformation has a higher heat of formation than the other conformations because of the steric repulsion between hydrogen atoms of neighboring phenyl rings.
