A spin-frustrated (4, 12)-connected metal-organic framework with unusual {Co8(μ4-OH)6}10 + cubes

A (4, 12)-connected metal-organic framework was solvothermally constructed from unusual CoII8 cubes, octahedral CoII1 subunits, and μ3-N1,N2,N4-triazolate connectors. Strong antiferromagnetic coupling between the neighboring CoII ions results in the absence of long-range magnetic ordering, leading to strong spin-frustration.212
