A two-dimensional copper(II) coordination polymer based on 2,4′-oxybis(benzoate) and 4,4′-bi­pyridine

The reaction of Cu(NO₃)₂·3H₂O with 2,4′-oxybis(benzoic acid) and 4,4′-bi­­pyridine under hydro­thermal conditions produced a new mixed-ligand two-dimensional copper(II) coordination polymer, namely poly[[(μ-4,4′-bi­pyridine-κ²N,N′)[μ-2,4′-oxybis(benzoato)-κ⁴O²,O^2′:O⁴,O^4′]copper(II)] monohydrate], {[Cu(C₁₄H₈O₅)(C₁₀H₈N₂)]·H₂O}_n, which was characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis and single-crystal X-ray diffraction. The X-ray diffraction crystal structure analysis reveals that the Cu^II ions are connected to form a two-dimensional wave-like network through 4,4′-bi­pyridine and 2,4′-oxybis(benzoate) ligands. The two-dimensional layers are expanded into a three-dimensional supra­molecular structure through inter­molecular O—H...O and C—H...O hydrogen bonds. Furthermore, magnetic susceptibility measurements indicate that the complex shows weak anti­ferromagnetic inter­actions between adjacent Cu^II ions.

Special details

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.
