Various propenoic acid stereoisomers 2,3-disubstituted with thienyl and/or phenyl groups were synthesised and their aggregation behaviour
was studied both in solution and in the solid state by experimental
(mid-range FT-IR spectroscopy) and computational (semiempirical and ab
initio) methods. Experimental approach embraced the identification of
potential hydrogen bonding sites through finding the relevant IR bands
and monitoring their displacement upon increasing the acid concentration
in solution and on going from solution to the solid state. In solution
O-H center dot center dot center dot O hydrogen bonds were only found
providing short-range ordering, while in the solid state C-H center dot
center dot center dot S hydrogen bonds were identified. Hydrogen bonding
sites could be assigned and relevant aggregate models could be built.
Molecular modelling allowed obtaining good estimates for hydrogen bond
lengths and angles and visualisation of the geometric arrangements. (C)
