由MCl_2(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

Synthesis,Structure and Properties of Two Two-Fold Interpenetrating 2D Coordination Polymers Constructed from MCl_2(M=Zn,Cd) with Imidazole-4,5-dicarboxylic Acid and 1,4-Bis(imidazol-1-yl)butane

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)Cl].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）CI]-H20}, （1）and 2D cadmium（H） coordination polymer [Cd2（HIDC）（bib）LsC12]n （2） （H3IDC=imidazole-4,5-dicarboxylic acid, bib=l,4-bis （imidazol-l-yl）butane） were obtained by the hydrothermal reactions of H3IDC, bib and ZnC12 or CdC12 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.
