Abstract
The crystal structure of (+/-)-2, 3-dihydro-3-oxo-1H-indeneacetic acid , C11H10O3, involves carboxyl-to-ketone hydrogen-bonding catemers [O . .. O 2.691(2) Angstrom] of an unusual type. Hydrogen bonds progress fr om the carboxyl H atom of one molecule to the ketone O (O1) atom of a glide-related enantiomer, resulting in heterochiral chains. Parallel s crew-related hydrogen-bonding chains proceed in counter-directional pa irs through the cell. Two different close contacts (2.49 and 2.58 Angs trom) are found between the carboxyl C=O group and H atoms on neighbor ing molecules.
