Abstract top

The asymmetric unit of the title polymeric compound, {[Cu(C22H18N2O4)(H2O)2]·H2O}n, contains a Cu ion situated on an inversion center, half of a centrosymmetric 4,4'-[1,4-phenylenebis(methyleneimino)]dibenzoate ligand, a coordinated water molecule in a general position and an uncoordinated water molecule situated on a twofold rotation axis. The distorted octahedral coordination geometry of the CuII ion is formed by six O atoms. The -NH- groups of the ligand are involved in intramolecular N-H...O hydrogen bonds, while the water molecules participate in the formation of a three-dimensional supramolecular framework via intermolecular O-H...O hydrogen bonds.

Comment top

In recent years, 4,4'-(1,4-phenylenebis(methylene))bis(azanediyl)dibenzoic acid and its ramifications have become an area of interest owing to their various properties (Yamaguchi et al., 1991; Imhof & Göbel, 2000). They are also used for building up supramolecular networks through hydrogen bonds (Jing et al., 2006). Of special interest are the low-dimensional structural motifs related with highly anisotropic physical properties. Here we report the crystal structure of the title compound, (I).

For the title polymeric compound, (I), structure determination revealed a presence in the asymmetric unit of a half of centrosymmetric 4,4'-(1,4-phenylenebis(methylene))bis(azanediyl)dibenzoic ligand, one Cu ion lies on the inversion ctnter, one coordinated water molecule locates on the twofold axis and one lattice water molecule locates in the general positon. The Cu ion is coordinated by six oxygen atoms with four of which from 4,4'-(1,4-phenylenebis(methylene))bis(azanediyl)dibenzoic ligand and the other two from water moleculers into a distorted octahedral geometry (Table 1). The neighbouring Cu ions are linked by 4,4'-(1,4-phenylenebis(methylene))bis(azanediyl)dibenzoic ligand to form an infinite plolymeric zigzag chain (Fig. 1). The amino groups of the ligand are involved in intramolecular N—H···O hydrogen bonds, wihle water molecules participate in formation of three-dimensional supramolecular framework via intermolecular O—H···O hydrogen bonds (Table 2).

Experimental top

The 10 ml aqueous solution of CuCl2.2H2O (0.855 g, 5 mmol) was droped into a 10 ml DMF soution of 4,4'-(1,4-phenylenebis(methylene))bis(azanediyl)dibenzoic acid (1.882 g, 5 mmol). The mixture was stirred for half an hour. The resultant solution was filtered, and the filtrate was allowed to stand at room temperature for one week, to generate blue block crystals.

Refinement top

C-bound H atoms were geometrically positioned (C-H 0.93-0.97 Å) and treated as riding on their parent atoms, with Uiso(H) = 1.2Ueq(C) Water H atoms were positioned geometrically with O—H = 0.85 Å and Uiso(H) = 1.2Ueq(O). The N-bound H atom was located on a difference Fourier map, but placed in idealized position (N-H 0.84 Å) and refined as ridinh with Uiso(H) = 1.5Ueq(N).

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.
