6-Nicotinamido-2-naphthoic acid

In the title molecule, C17H12N2O3, the naphthalene ring system and the pyridin-3-yl rings are nearly coplanar with a dihedral angle between them of 2.28 (8)°. In the crystal, the hydroxy and amide N atoms participate in hydrogen bonds, which connect the molecules into a two-dimensional network parallel to (101).
