In the title compound, C9H8NO+·C3H3O4−, the cation and anion are each essentially planar, with maximum deviations of 0.043 (1) and 0.060 (1) Å, respectively. The dihedral angle between these two planes is 2.20 (4)°. The conformation of the anion is stabilized by an intra­molecular O—H⋯O hydrogen bond, which forms an S(6) ring motif. The hy­droxy group of the oxine unit makes a hydrogen bond with the one of the O atoms of the carboxyl­ate group of the 2-carb­oxy­acetate anion. Two other carboxyl­ate O atoms form R22(7) ring motifs via inter­molecular C—H⋯O and N—H⋯O hydrogen bonds. The crystal structure is consolidated by weak inter­molecular C—H⋯O inter­actions, which link the cations and anions into a three-dimensional network.

Comment top

Recently, much attention has been devoted to the design and synthesis of supramolecular architectures assembled via various weak noncovalent interactions in the crystal structures of oxines (8-hydroxyquinoline), their derivatives and their complexes in a variety of crystalline environments (Balasubramanian & Muthiah, 1996a,b). Oxine is widely used as analytical reagent. The present study is aimed at understanding the hydrogen-bonding networks in the title compound, (I).

The asymmetric unit of title compound, (Fig. 1), consists of a 8-hydroxyquinolinium cation and a 2-carboxyacetate anion. 8-Hydroxyquinolinium is protonated at atom N1 leading to an enhancement of the internal angle [122.14 (11)°] at C1—N1—C2 compared with neutral quinoline moieties (Banerjee et al., 1984). The 8-hydroxyquinolinium cation and 2-carboxyacetate anion are essentially planar, with a maximum deviation of 0.043 (1) Å for atom C8 and 0.060 (1) Å for atom C11, respectively. The diheral angle between these two planes is 2.20 (4)°, indicating they are approximately parallel to each other. The anion is stabilized by an intramolecular O2–H1O2···O4 hydrogen bond, which forms an S(6) ring motif (Bernstein et al., 1995).

In the solid state (Fig. 2), carboxylate oxygen atoms (O4 and O5) form R22(7) ring motifs via intermolecular C2–H2A···O4 and N1–H1N1···O5 hydrogen bonds. The hydroxy group (O1–H1O1) of the oxine moiety makes a hydrogen bond with the O5 atom of the carboxylate group of the 2-carboxyacetate anion. The crystal structure is consolidated by weak intermolecular C2–H2A···O2 and C6–H6A···O3 interactions. The cations and anions are linked by these interactions into three-dimensional network.

Experimental top

A hot methanol solution (20 ml) of 8-hydroxyquinolinine (29 mg, Merck) and malonic acid (20.8 mg, Acros) was mixed and warmed over a magnetic stirrer hotplate for a few minutes. The resulting solution was allowed to cool slowly at room temperature and crystals of the title compound appeared after a few days.

All H atoms were located in a difference Fourier map and refined freely.

Experimental. The crystal was placed in the cold stream of an Oxford Cyrosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

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.
