摘要
采用3,5-bi(4-carboxy-phenoxy)-benzoic acid(H3BCPBA)为配体,以Mn为中心离子采用自组装的方法合成了配位聚合物{[Mn(H2BCPBA)2(H2O)4]}n,采用单晶衍射仪,红外光谱,热重,固体紫外和元素分析对其进行了晶体结构的解析和表征。它属于三斜晶系,P1空间群,晶胞参数分别为a=0.58423(13)nm,b=1.3644(3)nm,c=1.3910(3)nm,α=109.173(2)°,β=98.927(3)°,γ=99.123(3)°,V=1.0082(4)nm,Mr=913.63,Z=1,Dc=1.505 g/cm3,μ=0.414 mm-1,F(000)=471.0。热重分析表明,该配合物在410℃下稳定,UV固体光谱表明,该配合物有很弱的吸收。
A novel coordination complex {[Mn（H2BCPBA）2（H2O）4]}n（1,H3BCPBA=3,5-bi（4-carboxy-phenoxy）-benzoic acid） was synthesized from H3BCPBA and Mn2＋ by self-assembly method.The compound was characterized by elemental analysis,IR,UV spectroscopy and single crystal X-ray diffraction analysis.Single crystal X-ray analysis reveals that the title compound is crystallized in the triclinic system,space group P1 with a=0.58423（13） nm,b=1.3644（3） nm,c=1.3910（3） nm,α=109.173（2）°,β=98.927（3）°,γ=99.123（3）°,V=1.0082（4） nm,Mr=913.63,Z=1,Dc=1.505 g/cm3,μ=0.414 mm-1,F（000）=471.0 for 3470 observed reflections with I2σ（I）.TG shows that the title compound is stable under 410 ℃.UV spectroscopy study reveals that the complex exhibits weak ultraviolet absorption in the solid state at room temperature.
