摘　　要：A new metal-organic framework, {[Cd（DPA）（OBA）]＇（HzO）}n （1, DPA = 4,4＂-dipyri- dylamine, H2OBA = 4,4＂-oxybisbenzoic acid）, has been synthesized and characterized by elemental analysis, IR and single-crystal X-ray diffraction. Single-crystal X-ray analysis shows that it is a 3-D framework. Complex 1 crystallizes in monoclinic, space group C2/c with a = 21.699（7）, b = 12.192（4）, c = 17.566（5） A, β = 105.254（5）°, V = 4483.43 A3, Z = 8, Dc = 1.653 g/cm3, p = 1.021 mm^-1], F（000） = 2240, the final R = 0.0307, wR = 0.0867 （I 〉 2σ（I））. Complex I exhibits a rare three-dimensional highly 8-connected LOMFOI topology with a point symbol of {424＂64}. Thermogravimetric analysis shows that the decomposition temperature of the host framework of the complex is above 400 ℃.A new metal-organic framework, {[Cd（DPA）（OBA）]＇（HzO）}n （1, DPA = 4,4＂-dipyri- dylamine, H2OBA = 4,4＂-oxybisbenzoic acid）, has been synthesized and characterized by elemental analysis, IR and single-crystal X-ray diffraction.
