摘要:

在水热条件下, 以[PMo12O40]3-为模板, 合成了一个例新型二维层状化合物[Dy(BMBCP)(H2O)4]·[PMo12O40]·2.75H2O[HNU-7, H2BMBCP·Cl2=1,4-双(4-羧酸吡啶基-1-亚甲基)苯二氯], 并通过X射线单晶结构解析、 红外光谱(IR)、 电感耦合等离子体光谱(ICP)、 X射线粉末衍射(XRD)和荧光光谱对该化合物结构进行表征. 由于客体分子[PMo12O40]3-与配体BMBCP中的N+之间存在静电吸引力, 导致了-Dy2簇-BMBCP-Dy2簇-交替排列的螺旋链的形成. 左手螺旋链和右手螺旋链通过共同的Dy2簇进一步构筑成层状的4,4-网格结构.

Abstract:

A new two-dimensional(2D) Dy(Ⅲ) complex, [Dy(BMBCP)(H2O)4][PMo12O40]·2.75H2O{H2BMBCP=1,1'-[1,4-phenylene-bis(methylene)]-bis(pyridine-4-carboxylicaicd)}, denoted as HNU-7, was hydrothermally synthesized using [PMo12O40]3- as template, and characterized by single crystal X-ray diffraction, Infrared spectroscopy(IR), X-ray diffraction(XRD), inductively coupled plasa(ICP) and luminescent techniques. Interestingly, due to the electrostatic attraction between the guest ions [PMo12O40]3- and N+ of BMBCP ligands in the host sheets, pairs of helical -Dy2 cluster-BMBCP-Dy2 cluster-BMBCP- chains were formed by the alternation of Dy2 clusters and the BMBCP ligands. The left- and right-handed helical chains are linked together via Dy2 clusters to from the infinite sheet structure with 4,4-net.

Key words: Template, Hydrothermal synthesis, Host-guest system, Helical structure
