Abstract:

Two copper coordination polymers, Cu3(2,2′-bipy)2(C8H4O4)2(C8H5O4)2(1) and Cu(Ⅰ)Cu(Ⅱ)(4,4′-bipy)1.5(C8H4O4)(C8H5O4) were hydrothermally synthesized in mixed solvothermal and characterized by single crystal X-ray diffraction. Cu3(2,2′-bipy)2(C8H4O4)2(C8H5O4)2(1) crystallizes in a triclinic system with space group P1 and cell parameters, a=1.03314(4) nm, b=1.08350(3) nm, c=1.15826(4) nm, α=83.104(2)°, β=84.609(2)°, γ=66.125(2)°, and Z=1. Cu(Ⅰ)Cu(Ⅱ)(4,4′-bipy)1.5(C8H4O4)(C8H5O4)(2) crystallizes also in a triclinic system with space group P1 and cell parameters, a=1.06979(3) nm, b=1.09209(3) nm, c=1.47887(3) nm, α=91.795(2)°, β=93.2460(10)°, γ=118.6170(10)°, and Z=2. Their syntheses were performed under the similar conditions from different organic alkali ligands 2,2′-bipy and 4,4′-bipy at different concentrations. These changes gave rise to the corresponding change in final crystal structure of products. Both compounds are thermally stable up to 300 ℃.
