Misassigned C-H...Cu agostic interaction in a copper(II) ephedrine derivative is actually a weak, multicentred hydrogen bond.
Agostic interactions and weak hydrogen bonds to metal acceptors, M, are chemically and geometrically distinct, and this distinction must be maintained in the classification of new C-H...M interactions.
