摘  要:Two compounds have been obtained by the reaction of metal(Cu(II)), 4,4'-bis(imidazol-l-yl)diphenyl thioether(BIDPT) with two carboxylic acids, 4,4'-oxydibenzoic acid(H2oba) and phthalic acid(H2pht). The crystal structures of the resulting compounds, namely {[Cu(BIDPT)(oba)]·H2O}n(1) and {Cu(BIDPT)(pht)}n(2), have been determined by single-crystal X-ray diffraction analysis. Compound 1 is of orthorhombic system, space group Pbcn with a = 27.8310(3), b = 10.7791(1), c = 19.3913(2)A, V = 5817.0(3) ?3 and Mr = 656.15. Compound 2 belongs to the monoclinic system, space group C2/c with a = 18.2678(2), b = 11.0259(1), c = 22.906(2) A, β = 97.727(2)o, V = 4571.8(8) A3 and Mr = 545.04. Structural analyses reveal that compounds 1 and 2 respectively exhibit two-dimensional(2D) wavy and corrugated layer structures. Through intermolecular hydrogen bonding, compound 1 is assembled into a 3D supramolecular structure. The thermal stability and ultraviolet spectroscopy properties of the two compounds are also investigated.Two compounds have been obtained by the reaction of metal(Cu(II)), 4,4'-bis(imidazol-l-yl)diphenyl thioether(BIDPT) with two carboxylic acids, 4,4'-oxydibenzoic acid(H2oba) and phthalic acid(H2pht).
