In (rac)-MPOT crystals, the thioamide groups of the enantiomeric (4S,5R)- and (4R,5S)-MPOT pairs are hydrogen-bonded around a center of symmetry to form a planar cyclic dimer. On the other hand, a cyclic dimer through the hydrogen bonding is formed between the two independent molecules (molecules A and B) and its geometry is considerably distorted in (4S,5R)-MPOT crystals. 2003 © The Japan Society for Analytical Chemistry., 金沢大学理工研究域物質化学系}, pages = {x15--x16}, title = {Crystal structures of chiral and racemic 4-methyl-5-phenyl-1,3-oxazolidine-2-thione}, volume = {19}, year = {2003} }
