Abstract
C.I. Pigment Red 266, or 4-[[4-(aminocarbonyl)phenyl]hydrazono]-N-(2-methoxyphenyl)-3-oxo-3,4-dihydronaphthalene-2-carboxamide, C(25)H(20)N(4)O(4), adopts the keto-hydrazone tautomeric form with significant intramolecular hydrogen bonding. The molecules pack to form layers involving an extensive network of intermolecular hydrogen bonds, in which the primary amide group plays a prominent role. The good technical performance of this pigment in application may be attributed principally to the pattern of intra- and intermolecular hydrogen bonding.
