【摘要】 采用水热合成的方法,以2,5-二羟基对苯二甲酸和Cu(NO3)2为原料合成了新型金属配合物[Cu(DHBDC)2(H2O)2]n(DHBDC=2,5-二羟基对苯二甲酸).使用元素分析、X射线单晶衍射、红外光谱和热重分析对其进行了表征.化合物属于单斜晶系,空间群C2/c,晶胞参数a=1.652(2) nm,b=0.547(8) nm,c=1.161(16) nm,α=90°,β=108.924(2)°,γ=90°,Z=4,μ=2.231 mm-1,F(000)=596.0.配合物中,Cu2+是六配位模式,与2个2,5-二羟基对苯二甲酸和2个水分子配位.每个2,5-二羟基对苯二甲酸连接两个中心原子Cu并向两个方向延伸,形成一维链状结构.

【Abstract】 A new metal coordination polymer [Cu(DHBDC)2(H2O)2]n(DHBDC=2,5-dihydroxy benzene dicarboxylic acid) was synthesized by using DHBDC and Cu(NO3)2 through hydrothermal method.Elemental analysis, X-ray single crystal diffraction, infrared spectroscopy and thermogravimetric analysis were used for characterization.Single crystal analysis showed complex crystallizes in monoclinic system, C2/c space group with a=1.652(2) nm, b=0.547(8) nm, c=1.161(16) nm, α=90°,β=108.924(2)°,γ=90°,Z=4,μ=2.231 mm-1,F(000)=596.In the complex, Cu2+ is a six-coordinate mode, which is coordinated with two 2,5-dihydroxy benzene dicarboxylic acid and two water molecules.Each 2,5-dihydroxy benzene dicarboxylic acid connects two central atoms of copper and extends in both directions, forming a one-dimensional chain structure.
