Abstract: In the structure of the title complex, [Cs(C7H4NO2)(H2O)2]n, the caesium salt of 4-nitro­benzoic acid, the irregular CsO9 coordination sphere comprises three bridging nitro O-atom donors, a bidentate carboxyl­ate O,O'-chelate inter­action, a triple-bridging water mol­ecule and a monodentate water mol­ecule. A three-dimensional framework polymer is generated, within which there are water-carboxyl­ate O-H...O and water-water O-H...O hydrogen-bonding inter­actions.
