Abstract:The molecular structures of a series of 1,3-propanedithiols that contain
carboxylic acid groups, namely rac- and
meso-2,4-dimercaptoglutaric acid (H4DMGA) and
2-carboxy-1,3-propanedithiol (H3DMCP), have been determined by X-ray
diffraction. Each compound exhibits two centrosymmetric intermolecular hydrogen
bonding interactions between pairs of carboxylic acid groups, which result in a
dimeric structure for H3DMCP and a polymeric tape-like structure for
rac- and meso-H4DMGA.
Significantly, the hydrogen bonding … Show more
