| 摘要: 以对苯二甲酸(H2bdc)、邻菲咯啉(phen)和硫酸亚铁为原料,在水热条件下合成了一个新的配位聚合物[Fe(phen)(bdc)(H2O)]n,并对其进行了元素分析、红外光谱、紫外-可见光谱、热重和X-射线单晶衍射表征。该聚合物属于三斜晶系,P1空间群。每个Fe(Ⅱ)与2个N原子和3个O原子配位形成高度畸变的三角双锥结构,2个Fe(Ⅱ)由配体对苯二甲酸离子桥联为一维链状结构,链与链之间通过O-H…O氢键作用形成三维结构。荧光测试表明配合物在368 nm处有荧光发射。 |

| Abstract: A new coordination polymer [Fe(phen)(bdc)(H2O)]n has been hydrothermally synthesized and structurally characterized by elemental analysis, IR, UV-Vis, TG and single crystal X-ray diffraction analysis. It crystallizes in triclinic, space group P1, C20H14N2FeO5, with a=0.9308(6) nm, b=1.022 6(7) nm, c=1.134 1(5) nm,α=112.790(15)°, β=94.720(14)°, γ=113.417(10)°, V=0.876 9(9) nm3, Z=2, the final R1=0.0346, wR2=0.078 8. The Fe(Ⅱ) is coordinated with two nitrogen atoms and three oxygen atoms making a highly distorted trigonal bipyramidal. A 1D chain structure is constructed and further extended into a 3D structure through O-H…O intermolecular hydrogen bonding interactions. The polymer shows a fluorescence-emission at around 368 nm. CCDC: 894820. |
