Biphenyl-2,2′,4,4′-tetracarboxylic acid monohydrate

Abstract

In the title compound, C16H10O8·H2O, the dihedral angle between the two benzene rings is 71.63 (5)°. In the crystal structure, pairs of inversion-related molecules are stacked [mean interplanar spacing = 3.5195 (18) Å], and O—H...O and C—H...O hydrogen bonds create a three-dimensional network.
