5-(Naphthalen-1-yl)isophthalic acid-dimethyl sulfoxide-water (2/1/2)

A. Vetter, W. Seichter and E. Weber

Abstract: 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-H...O hydrogen bonds link the water molecules with the carbonyl and sulfoxide groups, giving rise to double ribbons along the b-axis direction.
