(a) ORTEPIII view of (IV-β), 3,7-dioxo-CA (molecule A), showing the displacement ellipsoids at 30% probability. (b) ORTEPIII view of (IV-β), 3,7-dioxo-CA (molecule B), showing the displacement ellipsoids at 30% probability. Among the three orientations of the carboxylic group, only the orientation with the greatest occupancy is shown. |
