The title compound, [Cs(CH₃COO)(C₂₈H₁₆O₈)(C₂H₅OH)].C₂H₅OH, is the product of the complexation between one vasarene analogue [1], bis ninhydrin naphthalene-1,3-diol and CsF, where the F- ion has reacted with residual acetic acid (AcOH), to form a [1].CsOAc complex. The intermolecular interactions with the multiple oxygen-containing functional groups of the ligand, as well as O-H. . .O hydrogen bonds involving the ethanol solvent molecules, stabilize the complex, forming a chain along [100]. Additional parallel-displaced .-. stacking, with an interplanar distance of 3.669 (1) Å , connect several unit cells in a three-dimensional supramolecular structure, though, the larger size of AcO- (1.60 Å ) compared to F- (1.33 Å ) prevents the tight packing that was once achieved with other vasarene complexes of CsF.
