水热合成了一种新型的(3，4，6)连通的三维多孔钴-有机骨架化合物{[Co2(HBIDC)2(Bpt)2]·7H2O}n(1)(H3bic=1H-苯并咪唑-5，6-二元酸，bpt=1H-3，5-双(4-吡啶)-1，2，4-三唑)，并用X-射线衍射仪对其结构进行了表征。化合物1具有Co-HBIDC层结构，其中的层被三维结构中的BPT间隔物柱撑，表现出Tn=10K的自旋倾斜弱铁磁性和长程磁有序的共存。
A novel (3,4,6)-connected 3D porous cobalt–organic framework formulated as {[Co2(Hbidc)2(bpt)2]·7H2O}n (1) (H3bidc = 1H-benzimidazole-5,6-dicarboxylic acid, bpt = 1H-3,5-bis(4-pyridyl)-1,2,4- triazole) has been hydrothermally synthesized and characterized by X-ray diffraction analysis. Compound 1, having a Co-Hbidc layer structure in which the layers are pillared by the bpt spacers in a 3D architecture, exhibits the coexistence of spin-canted weak ferromagnetism with TN = 10 K and long-range magnetic ordering.
