Pillared cobalt–organic framework with an unprecedented (3,4,6)-connected architecture showing the coexistence of spin canting and long-range magnetic ordering

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.
