Acta crystallographica. Section C, Crystal structure communications 1997 Dec 15The title compound, C14H12O6, crystallized in the centrosymmetric space group Pbca but does not exhibit hydrogen bonding of the usual cyclic dimer type about a center of symmetry or otherwise. Each molecule is linked to six neighbors by eight hydrogen bonds, which leads, in this structure, to a rich pattern of chains. Of the nine patterns of chains described, six propagate along the a direction, while three propagate along the c direction. The Odonor...Oacceptor distances in these hydrogen bonds are 2.683 (2), 2.706 (2), 3.011 (2) and 3.218 (3) A. In addition, each C-H group in the molecule is involved in one or more significantly attractive C-H...O interactions, while every O atom is involved in two or more. The two carboxylic H atoms are ordered, as are the carboxylic O atoms.
