The two bicyclic fragments of the title compound, C22H20N4O4, are individually planar and are turned with respect to each other by 77.8 (2)°. The formation of intramolecular O-H...O and N-H...O hydrogen bonds causes considerable changes in the bond lengths within the amido­pyridine fragment.

Comment top

In the present paper, we report the results of an investigation of the molecular and crystal structures of the (2-propyl-4-oxoquinazoline-3-yl)amide of 1-methyl-4-hydroxy-2-oxo-1,2-dihydroquinoline-3-carboxylic acid, (I), which may be used as efficient anti-inflammatory remedies (Ukrainets et al., 1993, 1994). Both bicyclic fragments of the molecule are planar. The amide group O3C10—N2 lies in the plane of the pyridine ring [the C1—C2—C10—N2 torsion angle is 2.8 (2)°]. This is caused by formation of O2—H2O···O3 and N2—H2N···O1 hydrogen bonds [H2O···O3 1.73 (4) Å, O2—H2O···O3 151 (4)°; H2N···O1 1.83 (3) Å, N2—H2N···O1 140 (2)°]. Two planar fragments are turned with respect to each other [the C10—N2—N3—C18 torsion angle is -77.8 (2)°]. The propyl substituent at the C11 atom and the C11—N4 bond have an sp orientation [the N4—C11—C20—C21 torsion angle is -0.4 (2)°]. Such an arrangement of the alkyl group, apparently, results from repulsion between the H atoms of the propyl substituent and the amide fragment. This assumption is confirmed by the presence of the shortened intramolecular contacts H20A···N2 2.60 Å and H20B···N2 2.61 Å (van der Waals radii sum is 2.66 Å; Zefirov et al., 1995). The formation of the intramolecular hydrogen bonds causes change of bond lengths within the amidopyridine fragment. Similar changes in the bond lengths were observed in the related structure 3-benzoyl-1-ethyl-4-hydroxy-2-quinolone (Borowiec et al., 1996). This effect may be explained by some contribution of the enole resonance form into the total structure of molecule.

Refinement top

All H atoms were located and their positional parameters were allowed to refine. The C—H distances are in the range 0.90 (2)–1.06 (5) Å, and N—H = 0.90 (3) Å and O—H = 0.83 (3) Å

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.
