Double Switching of a Magnetic Coordination Framework through Intraskeletal Molecular Rearrangement

Stairway to heaven: An Mn2Nb coordination framework shows huge switching of the magnetic ordering temperature in two well‐defined steps, finally reaching 100 K in its anhydrous form. The switching, controlled by removal/uptake of guest molecules, is related to an intraskeletal molecular rearrangemen...

Summary:Stairway to heaven: An Mn2Nb coordination framework shows huge switching of the magnetic ordering temperature in two well‐defined steps, finally reaching 100 K in its anhydrous form. The switching, controlled by removal/uptake of guest molecules, is related to an intraskeletal molecular rearrangement involving reversible formation/breaking of molecular bridges and translocation of an organic ligand on dehydration (see picture; VAC=vacuum).
