4,4′-[p-Phenylenebis(oxy)]dibutanoic acid
نویسنده
چکیده
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⋯π inter-actions between adjacent chains expand the structure into a layered network in the ac plane.

4,4'-(Disulfanediyl)dibutanoic acid (dtba) and 4,4'-bipyridine (4,4'-bpy) crystallize in an 1:1 ratio, leading to the title co-crystal with composition C8H14O4S2·C10H8N2. A distinctive feature of the crystal structure is the geometry of the dtba moiety, which appears to be stretched [with a 9.98 (1) Å span between outermost carbons] and acts as an hydrogen-bonding connector, forming linear chai...
