Crystal structure and Hirshfeld surface analysis of (E)-3-benzylidene-4-oxopentanoic acid

Abstract

The asymmetric unit of the title molecule, C12H12O3, contains two independent molecules having opposite conformations and each forming self-dimers through complementary O—H...O hydrogen bonds. These dimers are linked by weak C—H...π interactions and C—H...O hydrogen bonds into a three-dimensional structure in which one can discern layers parallel to the bc plane. A Hirshfeld surface analysis of the intermolecular interactions is included.
