通过水热合成法得到[Ag2(C6H4NO2)2]n配聚物的晶体结构。配合物为单斜晶系,P2(1)/c空间群,具有一维无限空间结构,其中两个Ag^+离子均为2配位,并且是晶体学不等效的。其重复单元由[Ag(1)(C6H4NO2)]和[Ag(2)(C6H4NO2)]两部分组成。Ag(2)与Ag(2)之间以及Ag(2)与Ag(1)之间存在多种弱键作用,使配合物形成了3D网络结构。同时也研究了配合物的发射、UV-VIS—NIR和IR等光谱。
Coordination polymers: [Ag2(C6H4NO2)2]n has been synthesized. The single crystal structure of the polymers was determined by X-ray diffraction. It crystallizes in the Monoclinic system, space group P2(1)/c. The polymers' structure is one dimension infinite, the two Ag^+ ions in the structure are both two-coordinate, and they are crystallographically unique. So the repetitive units of the polymers are consitituted of[Ag(1)(C6H4NO2)] and [Ag(2)(C6H4NO2)]. In the crystal structure, the INA ion connects Ag(1) to form 1D chain, and there are many weak interaction between Ag(2) and Ag(2) as well as Ag(2) and Ag(1), so the polymers have 3D network coordination frameworks. The fluorescence, phosphorescence, UV-VIS-NIR and IR spectra of the polymers was measured and analyzed.
