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 π–π stacking, with an inter­planar distance of 3.669 (1) A, connect several unit cells in a three-dimensional supra­molecular structure, though, the larger size of AcO− (1.60 A) compared to F− (1.33 A) prevents the tight packing that was once achieved with other vasarene complexes of CsF.
