the 3D pcu frameworks. In 1 the unusual pentanuclear [Zn5(μ3-OH)2(COO)8] secondary building units (SBUs) are linked by dicarboxylate ligands. Differently, in 3 the well-known paddle–wheel [Zn2(COO)4] SBUs are linked by dicarboxylate and dipyridyl ligands. Compound 2 shows the rare self-catenated 3D alb-3,6-C2/c net topology based on the dinuclear paddle–wheel SBU and a mononuclear unit. The stability
从一个新的二羧酸盐配体,9 ħ -咔唑-2,7-二羧酸(2,7--H 2 CDC),三个锌(II)的金属-有机骨架在不存在或双中心N-供体配体的存在下合成。它们配制设为[Zn 5(μ 3 -OH)2(2,7-二CDC)4(DEF)2 ](1)(DEF = Ñ,Ñ -diethylformamide),[锌2(2,7- CDC)2(DABCO)(H 2 O)]·5DMF·H 2 O(2)(DABCO = 1二氮杂-双环[2.2.2]辛烷,DMF = ñ,ñ二甲基甲酰胺),并且,[Zn2(2,7- CDC)2(BPEA)]·3DMA·2小时2 O(3)(BPEA = 1,2-双(4-吡啶基)ethylane,DMA = Ñ,Ñ二甲基乙酰胺)。化合物1个3显示的3D PCU框架。在1异常pentanuclear [锌5(μ 3 -OH)2(COO)8 ]次级结构单元(的SBU)由二羧酸酯的配体相
