Phenanthrene-4-carboxylic Acid and 1,2-Dihydrophenanthrene-4-carboxylic Acid
Acta Crystallographica Section C Crystal Structure Communications, 1998Phenanthrene-4-carboxylic acid, C15H10O2, crystallized in the centrosymmetric space group P2(1)/n, while 1,2-dihydrophenanthrene-4-carboxylic acid, C15H12O2, crystallized in the centrosymmetric space group Pbca. In each structure, there is a single type of hydrogen bond: it is of the cyclic dimer type about a center of symmetry.

2,6-Diphenylpyridine-4-carboxylic acid
Acta Crystallographica Section C Crystal Structure Communications, 2001The distinctive feature of the crystal structure of 2,6-diphenylpyridine-4-carboxylic acid, C18H13NO2, is the formation of intermolecular O-H...O hydrogen bonds that lead to the formation of centrosymmetric cyclic dimers with R2(2)(8) topology. Molecules related by translation along the b axis exhibit strong pi-pi stacking of aromatic rings, with an ...
