Abstract

In molecules of 3-nitrophthalic acid, C8H5NO6, the 2-carboxyl group, which is the central of the three substituents, is almost orthogonal to the arene ring, while the other two substituents are effectively coplanar with the ring. The molecules are linked by two O-H...O hydrogen bonds [H...O = 1.86 and 1.89 Angstrom, O...O = 2.6983 (13) and 2.6809 (12) Angstrom, and O-H...O = 172 and 155degrees] into sheets containing alternating R-2(2) (8) and R-6(6) (36) rings; these sheets are linked into a three-dimensional framework by a single C-H...O hydrogen bond [H...O = 2.41 Angstrom, C...O = 3.2663 (15) Angstrom and C-H...O = 150degrees].
