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.

Comment top

4-Nitrobenzoic acid (PNBA) has proved to be a useful ligand for the preparation of metal complexes, which are mainly monomeric but rarely involve the nitro group in coordination. With the known alkali metal salts of PNBA, the sodium salt (a trihydrate) (Turowska-Tyrk et al., 1988) and the potassium salt (a 1:1 salt-acid adduct) (Srivastava & Speakman, 1961), coordination polymeric structures are formed, but the structures of the rubidium and caesium salts have not been reported. The reaction of 4-nitrobenzoic acid with caesium hydroxide in aqueous ethanol afforded good crystals of the title Cs complex, [Cs(C7H4NO2)(H2O)2]n and the structure is reported herein.

In this structure (Fig. 1), the irregular CsO9 coordinate polyhedron comprises a bidentate carboxylate O,O'-chelate interaction, three O-donors from an O,O'-bridging nitro group, three O donors from a triple-bridging water molecule (O2W) and a monodentate water molecule (O1W) [Cs—O, 3.047 (4)–3.338 (4) Å] (Table 1). The bridging extensions in the two-dimensional sheet substructures which extend along the (0 0 1) plane include a centrosymmetric water–carboxyl quadruple cage (Fig. 2) (Cs···Csiii = 4.2610 (6) Å] [for symmetry code (iii), see Table 2]. The p-related carboxyl and nitro substituent groups of the PNBA ligand link the sheets across c, and generate an overall a three-dimensional coordination polymer (Fig. 3). This type of structure extension through the p-related benzoate carboxyl and nitro functional groups is similar to that found in other alkali metal complexes with the 4-nitroanthranilate salts of sodium (a dihydrate) and potassium (a monohydrate) (Smith, 2013), and caesium (a monohydrate) (Smith & Wermuth, 2011).

The crystal structure of the title complex polymer is stabilized by intra-sheet water O—H···Ocarboxyl and O—H···Owater hydrogen-bonding interactions (Table 2). No inter-ring ππ interactions are present [minimun ring centroid separation 4.643 (2) Å]. The PABA ligand in the complex is essentially planar [torsion angles C2—C1—C11—O12 = 177.9 (4)° (carboxyl) and C3—C4—N41—O41 = 177.5 (4)° (nitro)]. This conformation is similar to that found in both monoclinic polymorphs of the parent acid [Tonogaki et al., 1993; Groth, 1980; Bolte, 2009].

Experimental top

The title compound was synthesized by heating together for 10 minutes, 0.5 mmol of 4-nitrobenzoic acid and 0.5 mmol of CsOH in 15 ml of 10% ethanol–water. Partial room temperature evaporation of the solution gave colourless elongated crystal plates of the title complex from which a specimen was cleaved for the X-ray analysis.

Refinement top

Carbon-bound hydrogen atoms were placed in calculated positions [C—H = 0.95 Å] and allowed to ride in the refinement, with Uiso(H) = 1.2Ueq(C). Hydrogen atoms of the coordinated water molecule were located in a difference Fourier map but were subsequently allowed to ride, with Uiso(H) = 1.5Ueq(O).

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
