Claim: Although distinguished when they act as ligands for transition metals, the names amides and imidic acids are synonyms describing two different anions.
Evidence: However, they are distinguished when they act as ligands for transition metals, with O-bound species referred to as imidates and N-bound species referred to as amidates. Since amides and imidic acids are tautomers, they form the same anion upon deprotonation. An amidate/imidate anion is formed upon deprotonation of an amide or imidic acid.
