The metal complexes with the derivatives of the cinnamic acid have been structurally characterized. The geometry of metal–ligand interaction has been determined by X‐ray absorption fine structure spectroscopy. The Co(II) complex with 4‐methoxycinnamic acid has the octahedral geometry with four carboxylate groups of cinnamate anions and two water molecules in the coordination sphere. Moreover, the Cu(II) complex with 4‐nitrocinnamic acid has been synthesized and characterized. In this compound, a square geometry around metal cation is formed by the carboxylate groups from two monodentate ligands and two water molecules. Copyright © 2015 John Wiley & Sons, Ltd.
