8-Hydroxyquinoline (1.5 g, 10.3 mmol) and anhydrous potassium carbonate (1.6 g, 11.6 mmol)were added to DMF (15 mL), then 2-chloro-N-methyl-N-phenylacetamide (1.83 g, 10.0 mmol, Zhi et al., 2011) and a small quantity of KI were added. The reaction mixture was stirred for 5 h at 100–110 °C. After cooling down, 150 mL water was added and stirred for 2 h. The precipitate was collected by filtration and washed with water. Recrystallization from EtOH/H2O (1:1) gave colorless blocks.
C-bound H atoms were placed in calculated positions (C—H = 0.93 and 0.97 Å) and were included in the
in the riding model approximation, with Uiso(H) = 1.2Ueq(C). The water H atoms were located from difference Fourier map calculation and then refined unsing DFIX and DANG instruction, with O—H = 0.85Å and Uiso(H) = 1.5Ueq(O). DELU, SIMU and ISOR restraints have been applied on the Uij-values of the C atoms.Data collection: APEX2 (Bruker, 2007); cell

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. |

The amide type open-chain ligands have attracted much attention mainly because their excellent coordination ability and high selectivity to metal ions. Lanthanide complexes usually exhibit fascinating properties that may have potential applications in biology, medicine, and material science (Li et al., 2003). The luminescent properties of lanthanide complexes with amide type ligands have been investigated in our previous work (Wu et al., 2008). As part of our ongoing studies of the amide type ligands, the title compound was synthesized and characterized by X-ray diffraction.
In the title compound, all bond lengths are comparable with those observed in a similar compound (Li et al., 2005). The dihedral angle between the quinoline ring (N1/C1–C9, r.m.s. deviation 0.0038 Å) and the benzene ring(C13–C18, r.m.s. deviation 0.0049 Å) is 87.19 (8)°. In the crystal structure, solvent water molecules form intermolecular O—H···N and O—H···O hydrogen bonds with acetamide molecules to stabilize the packing (Table 1).
