Source of material

The title compound, was prepared by the reaction of 4-fluorobenzaldehyde, 4-hydroxyquinolin-2(1H)-one, and 1H-indazol-6-amine, with the method described in literature [1]. Crystals suitable for X-ray diffraction were obtained by slow evaporation of a DMF/H2O solution.

Experimental details

The H atoms were calculated geometrically and refined as riding, with C—H = 0.93–0.98 Å, except for H1A, H1B, H1, H3 and H4, and with Uiso(H) = 1.2Ueq(parent atom, 1.5Ueq for methyl groups).

Discussion

Imidazoles and naphthyridines are important pharmaceutical molecules [2, 3]. In the crystal structure of the title compound, the central pyridyl ring adopts a skew-boat confirmation. The atoms of C5, C6, C14 and C16 are coplanar, with atoms N3 and C15 deviating from the defined plane by −0.144(2) and −0.308(3) Å, respectively. The adjacent quinoline and indazole moieties are planar (Figure 1), with mean deviation being 0.023(1) and 0.012(1) Å, respectively. The pyridine ring is nearly perpendicular to the phenyl ring (C18-C23), making a dihedral angle of 88.1(1)°.

There are four inter molecular hydrogen bonds between the hexacyclic molecule and the solvent molecules DMF and H2O. The atom O5 in DMF forms two hydrogen bonds of N3—H3⋯O5 and C8—H8A⋯O5, while the target molecule is conneted to a molecule of H2O via the hydrogen bond of N4—H4⋯O3. This molecule of H2O links another molecule of DMF though the fourth hydrogen bond as shown in Figure 2.
