摘要
利用水热技术,以MnCl2.4H2O、水杨酸(H2Sal)和二吡啶[3,2-a:2′,3-′c]并吩嗪(DPPZ)为原料,合成了具有三维超分子网络结构的新型配合物[Mn2(HSal)2(Sal)(DPPZ)2(H2O)2]2[Mn4(Sal)4(DPPZ)4(H2O)2],并使用元素分析和X射线单晶衍射对其结构进行了表征.该晶体属于三斜晶系,Pī空间群,a=13.8342(11),b=15.7681(13),c=23.1455(19),α=89.8250(10)°,β=83.9240(10)°,γ=64.286 0(10)°,V=4518.2(6)3,Z=1.该化合物是由两个双核和一个四核Mn(Ⅱ)结构单元构筑的,而且在相邻的配合物分子单元之间,存在着分子内和分子间DPPZ配体不同方向上的π-π堆积作用,最终将其连接成一个三维超分子网络结构.
A novel complex [Mn2(HSal)2(Sal)(DPPZ)2(H2O)2]2[Mn4(Sal)4(DPPZ)4(H2O)2] ,with three-dimensional structure,based on salicylic acid (H2Sal) and dipyrido[3,2-a:2A,3A-c]phenazine (DPPZ) ligands has been hydrothermal synthesized and characterized by elemental analysis and single-crystal X-ray diffraction. The title compound crystallizes in trichnie space group Pī,with a = 13.834 2(11)A, b = 15.768 1(13) A, c = 23. 145 5(19) A, α = 89. 825 0(10)°,β = 83.924 0( 10)°,γ = 64. 286 0( 10)°, V = 451 8.2(6) A^3, Z = 1. The structure of the title compound features two dinuclear and a tetranuclear Mn( Ⅱ ) cluster unit.Also,the neighboring units are further linked into a 3 D supramolecular network via π-π interactions in the different directions between the DPPZ ligands.
