4,4'-[p-Phenyl-enebis(-oxy)]dibutanoic acid.


ABSTRACT: The complete mol-ecule of the title compound, C(14)H(18)O(6), has a center of inversion at the centroid of the benzene ring and the asymmetric unit contains one half-mol-ecule. The conformation of the side chain is anti [C-C-C-C = -171.40?(17)°]. In the crystal, pairs of head-to-head carb-oxy-lic acid O-H?O hydrogen bonds link the mol-ecules into infinite zigzag chains propagating along [130]. Weak C-H?? inter-actions between adjacent chains expand the structure into a layered network in the ac plane.
