由MCl2(M=Zn,Cd)与咪唑-4,5-二羧酸和1,4-双(咪唑-1-基)丁烷构筑的两个二重穿插二维配位聚合物的合成、结构和性质

摘要

以2∶1∶4物质的量比的咪唑4,5-二羧酸(H3IDC),1,4-双(咪唑-1-基)丁烷(bib)和ZnCl2或CdCl2为反应物,在水热条件下分别得到了1个二重穿插的二维锌(Ⅱ)配位聚合物{[Zn2(IDC)(bib)C1]· H2O}n (1)和1个二重穿插的二维镉(Ⅱ)配位聚合物[Cd2(HIDC)(bib)1.5Cl2]n(2).用元素分析、红外光谱以及单晶X-射线衍射结构分析对它们的组成和结构进行了表征,并对它们的热稳定性和荧光性质进行了初步的研究.%Two-fold interpenetrating 2D Zinc (II) coordination polymer {[Zn2(IDC)(bib)Cl]-H2O}n (1) and 2D cadmium(II) coordination polymer [Cd2(HIDC)(bib)I.5Cl2]n (2) (H3IDC=imidazole-4,5-dicarboxylic acid, bib=l,4-bis (imidazol-l-yl)butane) were obtained by the hydrothermal reactions of HJDC, bib and ZnCl2 or CdCl2 with 2:1:4 mole ratio, respectively. Their composition and structures were determined by elemental analysis, infrared spectroscopy, and single-crystal X-ray diffraction analysis. Their thermal stabilities and luminescent properties were investigated as well. CCDC: 772780, 1; 772781, 2.
