Abstract: In the title compound {systematic name: bis[2-(acetyloxy)benzoato-²O,O']diaquacadmium(II)}, [Cd(C₉H₇O₄)₂(H₂O)₂], the Cd^II ion is located on a twofold rotation axis and is coordinated by two water molecules and two aspirinate ligands. The complex is almost isostructural with the corresponding zinc(II) complex. However, for the title compound, the aspirinate should be considered as an asymmetric chelating ligand, with Cd-O(carboxylate) bond lengths of 2.2777 (12) and 2.4121 (12) Å.
