| description |
The asymmetric unit of the title compound, C22H26O8, contains two crystallographically independent molecules with closely comparable conformations (r.m.s. overlay = 0.54 Å for 30 non-H atoms). All six-membered rings display chair conformations, with a slight distortion for the lactone ring. The molecules are connected by O—H...O hydrogen bonds into chains along [010], with the independent molecules segregated into separate chains. The two molecules in the asymmetric unit face each other in a head-to-tail fashion, with the furan ring of one molecule turned towards the carboxylic acid terminal of the other molecule. |
