The asymmetric unit of the title compound, 2C18H12O4·C2H6OS·2H2O, consists of four crystallographically independent molecules of 5-(naphthalen-1-yl)isophthalic acid, two dimethyl sulfoxide and four water molecules. The dihedral angles formed by the the planes of the aromatic fragments of the organic molecules range from 57.4 (1) to 59.1 (1)°. In the crystal, multiple O—HO hydrogen bonds link the water molecules with the carbonyl and sulfoxide groups, giving rise to double ribbons along the b-axis direction.

In the title compound, C15H11N, the mean planes of the aromatic moieties are inclined to one another by 72.9 (1)°. The crystal is stabilized by π–π stacking interactions between the pyridine rings of inversion-related molecules, with a centroid–centroid distance of 3.772 (2) Å. In addition, C—Hπ contacts involving an α-C—H group of the pyridine ring and the nonsubstituted ring of the naphthalene unit are observed, giving rise to a herringbone-type supramolecular architecture of the naphthalene moiety being contained in the molecule.
