2-(2-Quinol­yl)quinolinium nitrate

Abstract

In the cation of the title compound, C18H13N2 +·NO3 , the two bicyclic ring systems form a dihedral angle of 3.84 (4)°. The nitrate anion is disordered over two orientations in a 0.9:0.1 ratio. In the crystal structure, the cations form stacks along the a axis, with short inter­molecular contacts [C(...)C = 3.330 (3) and 3.345 (4) Å], and link to the anions via N—H(...)O hydrogen bonds.

Comment

In recent years, there has been considerable interest in proton transfer systems and their structures (Smith et al., 1999; Zafar et al., 2000; Rafizadeh et al., 2006; Yousefi et al., 2007). To our knowledge, there is only one proton-transfer system with 2,2'-biquinolinyl, such as [(biq.H)(I2Cl3)] [biq.H = 2-(2-quinolinyl)quinolinium], which was structurally characterized (Parlow & Hartl, 1979). Herewith we report the synthesis and crystal structure of the title compound, (I).

The asymmetric unit of (I) contains one cation and one anion (Fig. 1). In the cation, two bicycles form a dihedral angle of 3.84 (4)%. In the crystal structure, the cations form stacks along the a axis with short intermolecular contacts [C···C = 3.330 (3) and 3.345 (4)Å] linking the anions via N—H···O hydrogen bonds.

Experimental

For the preparation of the title compound, (I), a solution of 2,2'-biquinolinyl (0.20 g, 0.78 mmol) in HNO3 0.5 M (10 ml) was added to a solution of La(NO3)3.6H2O, (0.11 g, 0.26 mmol) in water (5 ml) and the resulting yellow solution was stirred at 333 K for 2 h. Then, it was left to evaporate slowly at room temperature. The suitable crystals for X-ray diffraction experiment were obtained by methanol diffusion in a solution of yellow precipitated in DMSO after one week (yield 0.19 g, 76.2%, m.p 496–497 K).

Refinement

C-bound H atoms were geometrically positioned (C-H 0.95 Å). The H atom of NH group was located on a difference Fourier map, but placed in idealized position (N-H 0.91 Å). All H atoms were refined in riding model approximation, with Uiso(H) = 1.2 Ueq of the parent atom. The NO3 anion was treated as disordered between two orientations with the occupancies fixed to 0.9 and 0.1, respectively.

Special details

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.
