Abstract top

In the title molecule, C18H17N3O3, the dihedral angle between the mean planes of the furan ring and the quinoline group is 77.4 (2)°. In the crystal structure, intermolecular N-H...N hydrogen bonds link the molecules into centrosymmetric dimers.

Comment top

Synthsis of 8-Hydroxyquinoline and its derivatives have attracted a great interest due to their interesting biological activities and applications in coordination chemistry (Cai et al., 2003; Chen et al., 2005; Park et al., 2006; Karmakar et al. 2007). Herein, we report the synthesis and crystal structure of the title compound, (I). The molecular structure of (I) is shown in Fig. 1. The conformation along the O1—C10—C11—C12—C13—N2—N3—C14 bond sequence is (-)gauche-trans-trans-(-)gauche-trans. The mean planes of the furan ring and quinoline group make a dihedral angle of 77.4 (2) °. In the crystal structure (Fig. 2), intermolecular N—H···N hydrogen bonds (Table 1) link the molecules into centrosymmetric dimers. Some crystal structures which are closely related to the title compound have already been studied (Zheng, 2006; Zheng, Wu et al.,2006; Zheng, et al.,2007; Zheng, Li et al., 2006; Zheng, et al., 2008.

Experimental top

Reagents and solvents used were of commercially available quality. The title complex (I) was synthesized according to the method of Zheng (2006). 4-(Quinolin-8-yloxy)butanohydrazide (0.01 mol), furan-2-carbaldehyde (0.01 mol), ethanol (40 ml) and some drops of acetic acid were added to a 100 ml flask and refluxed for 6 h. After cooling to room temperature, the solid product was separated by filtration. Colourless single crystals suitable for X-ray diffraction study were obtained by slow evaporation of a tetrahydrofuran solution over a period of 2 d.

Refinement top

All H atoms were placed in idealized positions (C—H = 0.93–0.97Å and N—H = 0.86Å) and refined as riding atoms with Uiso(H) = 1.2Ueq(C,N). In the molecule, some anisotropic displacemnt parameters of the atoms are larger than normal and restraints were applied in the form of the DELU and SIMU instructions in the SHELXL (Sheldrick, 2008) program.

Special details top

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.
