Abstract top

In the title compound, [Cu(CH3COO)2(C18H16N2O2)]·H2O, the CuII ion is six-coordinated in a typically Jahn-Teller distorted octahedral environment defined by two O and two N atoms from the ligand and two O atoms from acetate anions. A linear chain structure propagating in [010] is built up by intermolecular O-H...O hydrogen bonds involving the uncoordinated water molecules.

Comment top

N-Heterocyclic ligands coordinated with transition metal ions can form a variety of topology structures, including macrocycles, polyhedra and linear and helical polymers. Our group has report three kinds of flexible pyridyl-based ligands in previous reports (Liu et al. 20010a; Liu et al. 20010 b). As a part of our continuing work for bipyridyl aromatic ligands, we report the crystal structure of the title compound here.

1,2-Bis(pyridin-2-ylmethoxy)benzene molecule act as a chelating ligand to coordinate with CuII ion forming a discrete strucutre. Two acetate counter ions also coordinate to the center CuII ion, resulting the CuII ion is six-coordinated in quadrangular bipyramid geometry (Figure 1, Table 1).

A one-dimensional chain structure is built up by intermolecular hydrogen bonds involving the uncoordinated water molecules (Figure 2, Table 2).

Experimental top

The 1,2-Bis(pyridin-2-ylmethoxy)benzene was synthesized by the reaction of ο-dihydroxybenzene and 2-chloromethylpyridine hydrochloride under nitrogen atmosphere and alkaline condition (Liu et al., 2010a). Title ligand (0.58 g, 2 mmol) and Cu(CH3COO)2.H2O (0.40 g, 2 mmol) were dissolved in 15 mL e thanol, and then the mixture keep stirring for 30 minute. The resulting solution was filtered, and the filtrate was allowed to stand in a desiccator at room temperature for several days. Bule needle crystals were obtained with yield 34 %.

Refinement top

H atoms bound to C atoms were placed in calculated positions and treated as riding on their parent atoms, with C—H = 0.93 Å (aromatic C), C—H = 0.97 Å (methene C), C—H = 0.98 Å (methyl C), and with Uiso(H) = 1.2Ueq(C). Water H atoms were initially located in a difference Fourier map but they were treated as riding on their parent atoms with O—H = 0.85 Å, and with Uiso(H) = 1.5Ueq(O).

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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.
