Abstract
The carboxylic acid group and the double bond are coplanar in (E)-3-(benzoxazol-2-yl)prop-2-enoic acid, C 10 H 7 NO 3 , whereas in isomeric (Z)-3-(benzoxazol-2-yl)prop-2-enoic acid, also C 10 H 7 NO 3 , they are almost orthogonal. In both isomers, a strong O-H...N hydrogen bond, with the carboxylic acid group as a donor and the pyridine-like N atom as an acceptor, and weak C-H...O interactions contribute to the observed supramolecular structures, which are completed by π-π stacking interactions between oxazole and benzenoid rings.
