| 摘要: 以4,4'-联苯咪唑(4,4'-bibp)和间苯二甲酸(H2MPA)为配体,采用水热法合成了1个二维镍(Ⅱ)配位聚合物[Ni(H2O)(MPA)(4,4'-bibp)]n(1)。通过元素分析、红外光谱、热重(TGA)和X-射线粉末衍射(PXRD)等手段对其进行了表征,并用X-射线单晶衍射法测定了配合物的单晶结构。该配合物属于单斜晶系,Pc空间群,为二维层状结构。我们研究了配体和配合物在室温下的固体紫外光谱性质。 |

| Abstract: A 2Dcomplex [Ni(H2O)(MPA)(4,4'-bibp)]n (1), based on mixed-ligands, bibp (bibp =4,4'-bisimidazolyl-biphenyl) and H2MPA (H2MPA=m-phthalic acid), has been synthesized by hydrothermal method and characterized by elemental analysis, IRspectra, TGA, XRD, and the crystal structure was determined by single-crystal X-ray diffraction. The complex crystallizes in the monoclinic system, space group Pc and features a 2D layered structure. The solid UV-Vis properties of ligands and the complex 1 were studied at room temperature.
