Biphenyl-3,3'-dicarb-oxy-lic acid.

ABSTRACT: The asymmetric unit of the title compound, C(14)H(10)O(4), contains one half mol-ecule, the complete mol-ecule being generated by a twofold axis. The two benzene rings form a dihedral angle of 43.11?(5)°. Inter-molecular O-H?O hydrogen bonds link the mol-ecules into one-dimensional zigzag chains. These chains are further connected into two-dimensional supra-molecular layers by weak ?-? stacking inter-actions between neighbouring benzene rings, with centroid-centroid distances of 3.7648?(8)?Å.
