title: Biphenyl-2,2',4,4'-tetra-carb-oxy-lic acid monohydrate.
abstract: In the title compound, C(16)H(10)O(8)·H(2)O, the dihedral angle between the two benzene rings is 71.63 (5)°. In the crystal structure, pairs of inversion-related mol-ecules are stacked [mean inter-planar spacing = 3.5195 (18) Å], and O-H⋯O and C-H⋯O hydrogen bonds create a three-dimensional network.
