In the crystal structure of the title compound, C17H17ClN4O, the existence of only one 2-imino–oxo of the five possible N-amino–imino/O-keto–hydroxy tautomers Washing Machine Idler Pulley is observed and the dihedral angle between the aromatic rings is 29.78 (11)°.The molecular conformation is stabilized by intramolecular C—H.
N, N—H.O and C—H.O hydrogen bonds, in each case generating a six-membered ring.
In the crystal structure, the glide-plane-related molecules are Gift Set linked into C(4) amide chains by intermolecular N—H.O hydrogen bonds, and an intermolecular C—H.O link also occurs.
