摘　　要：A new cooper benzenedicarboxylate metal-organic coordination polymer,[Cu（μH2O）（BDC）]n·nDMF（1,H2BDC = 1,4-benzenedicarboxylate acid,DMF = N,N＇-dimethylfor-mamide）,has been successfully synthesized under hydrothermal conditions and characterized by IR spectroscopy,elemental analysis,thermogravimetric analysis and single-crystal X-ray diffraction.This complex crystallizes in triclinic,space group P1 with a = 6.605,b = 10.44780（10）,c = 11.0881（6） ,α = 62.064（11）,β = 73.410（15）,γ = 78.404（16）°,C11H13CuNO6,Mr = 318.76,V = 645.79（8） 3,Z = 2,Dc = 1.639 g/cm3,F（000） = 326,μ = 1.712 mm-1,the final R = 0.0362 and wR = 0.1330 for 2055 observed reflections with I 〉 2σ（I）.The title compound contains infinite inorganic chains constructed by Cu oxygen octahedra by sharing corners and edges.Each chain is connected by BDC linkers to four other chains to form a three-dimensional framework with irregular rhombic channels where the DMF molecules are encapsulated.A new cooper benzenedicarboxylate metal-organic coordination polymer,[Cu（μH2O）（BDC）]n·nDMF（1,H2BDC = 1,4-benzenedicarboxylate acid,DMF = N,N＇-dimethylfor-mamide）,has been successfully synthesized under hydrothermal conditions and characterized by IR spectroscopy,elemental analysis,thermogravimetric analysis and single-crystal X-ray diffraction.This complex crystallizes in triclinic,space group P1 with a = 6.605,b = 10.44780（10）,c = 11.0881（6） ,α = 62.064（11）,β = 73.410（15）,γ = 78.404（16）°,C11H13CuNO6,Mr = 318.76,V = 645.79（8） 3,Z = 2,Dc = 1.639 g/cm3,F（000） = 326,μ = 1.712 mm-1,the final R = 0.0362 and wR = 0.1330 for 2055 observed reflections with I 〉 2σ（I）.The title compound contains infinite inorganic chains constructed by Cu oxygen octahedra by sharing corners and edges.Each chain is connected by BDC linkers to four other chains to form a three-dimensional framework with irregular rhombic channels where the DMF molecules are encapsulated.
