The structure of the title adduct compound, C10H8NO2+·C6H2N3O9S−·C10H7NO2, from the reaction of 2,4,6-trinitrobenzenesulfonic acid (picrylsulfonic acid) with quinoline-2-carboxylic acid (quinaldic acid) in 2-propanol–water, has been determined at 130 (2) K. The cation and the adduct species form a twisted cyclic hydrogen-bonded R22(10) pseudo-dimer which is extended into a one-dimensional chain structure through short head-to-tail carboxylic acid O—H⋯Ocarboxyl associations [O⋯O = 2.4711 (19) Å]. The picrylsulfonate anions are attached peripherally by single N—H⋯Osulfonate hydrogen bonds [N⋯O = 2.8643 (19) Å].

The title compound was synthesized by heating under reflux 1 mmol quantities of 2,4,6-trinitrobenzenesulfonic acid (picrylsulfonic acid) and quinoline-2-carboxylic acid (quinaldic acid) in 50 ml of 80% 2-propanol-water for 10 minutes. After concentration to ca 30 ml, partial room temperature evaporation of the hot-filtered solution gave pale yellow flat prisms of (I) [m.pt. 495–496 K].
Interactive hydrogen atoms were located by difference methods and their positional and isotropic displacement parameters were refined. The aromatic ring H atoms were included in the
in calculated positions (C–H = 0.95 Å) using a riding model approximation, with Uiso(H) = 1.2Ueq(C).Picrylsulfonic acid (2,4,6-trinitrobenzenesulfonic acid) reacts with certain Lewis bases to form 1:1 proton-transfer salts and the structures of a small number of these are known: with guanidine (Russell & Ward, 1997) and quinoline (Smith, Wermuth & Healy, 2006). However, the 1:1 reaction with quinoline-2-carboxylic acid in 80% 2-propanol-water resulted in the adduct salt 2-carboxyquinolinium-2,4,6-trinitrobenzenesulfonate-quinolinium- 2-carboxylate (1/1/1) (I) and the structure is reported here. In (I), the
comprises a protonated quinaldic acid cation (A), a picrylsulfonate anion and a zwitterionic quinaldic acid adduct molecule (B) (Fig. 1). The cation and the adduct species form a pseudo-dimer through a twisted cyclic hydrogen-bonded duplex N–H···O association [graph set R22(10) (Etter et al., 1990]. This pseudo-dimer incorporates a cyclic R22(4) association and two intramolecular S(5) N–H···Ocarboxyl associations and is similar to that found in the zwitterionic parent acid (Dobrzyńska & Jerzykiewicz, 2004), the 1:2 L-tartaric acid-quinaldic acid adduct (Smith, Wermuth & White, 2006) and in the analogous (1:1:1) protonated quinaldic acid-zwitterionic adduct compounds with 5-sulfosalicylic acid (Smith et al., 2004) and 4,5-dichlorophthalic acid (Smith, Wermuth & White, 2007). However, in the 1:1 compound with 3,5-dinitrosalicylic acid (Smith, Wermuth, Healy & White, 2007), this dimer is not found.In (I), the pseudo-dimers are extended into one-dimensional chain structures through short head-to-tail carboxylic acid O–H··· Ocarboxyl associations [O···O, 2.4711 (19) Å] (Fig. 2). The picrylsulfonate anions are attached peripherally by single N–H···Osulfonate hydrogen bonds (Table 1).
All nitro groups of the anion are rotated out of the plane of the benzene ring, particularly those which are ortho to the sulfonate group [torsion angle C1–C2–N2–O22, -139.19 (17) °; C5–C6–N6–O62, 115.70 (17) °], compared to the para- related group [torsion angle C3–C4–N4–O42, 165.79 (16) °].

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. |

Picrylsulfonic acid (2,4,6-trinitrobenzenesulfonic acid) reacts with certain Lewis bases to form 1:1 proton-transfer salts and the structures of a small number of these are known: with guanidine (Russell & Ward, 1997) and quinoline (Smith, Wermuth & Healy, 2006). However, the 1:1 reaction with quinoline-2-carboxylic acid in 80% 2-propanol-water resulted in the adduct salt 2-carboxyquinolinium-2,4,6-trinitrobenzenesulfonate-quinolinium- 2-carboxylate (1/1/1) (I) and the structure is reported here. In (I), the asymmetric unit comprises a protonated quinaldic acid cation (A), a picrylsulfonate anion and a zwitterionic quinaldic acid adduct molecule (B) (Fig. 1). The cation and the adduct species form a pseudo-dimer through a twisted cyclic hydrogen-bonded duplex N–H···O association [graph set R22(10) (Etter et al., 1990]. This pseudo-dimer incorporates a cyclic R22(4) association and two intramolecular S(5) N–H···Ocarboxyl associations and is similar to that found in the zwitterionic parent acid (Dobrzyńska & Jerzykiewicz, 2004), the 1:2 L-tartaric acid-quinaldic acid adduct (Smith, Wermuth & White, 2006) and in the analogous (1:1:1) protonated quinaldic acid-zwitterionic adduct compounds with 5-sulfosalicylic acid (Smith et al., 2004) and 4,5-dichlorophthalic acid (Smith, Wermuth & White, 2007). However, in the 1:1 compound with 3,5-dinitrosalicylic acid (Smith, Wermuth, Healy & White, 2007), this dimer is not found.
In (I), the pseudo-dimers are extended into one-dimensional chain structures through short head-to-tail carboxylic acid O–H··· Ocarboxyl associations [O···O, 2.4711 (19) Å] (Fig. 2). The picrylsulfonate anions are attached peripherally by single N–H···Osulfonate hydrogen bonds (Table 1).
All nitro groups of the anion are rotated out of the plane of the benzene ring, particularly those which are ortho to the sulfonate group [torsion angle C1–C2–N2–O22, -139.19 (17) °; C5–C6–N6–O62, 115.70 (17) °], compared to the para- related group [torsion angle C3–C4–N4–O42, 165.79 (16) °].
