Room-Temperature Organic-Based Magnet (Tc≈50 °C) Containing Tetracyanobenzene and Hexacarbonylvanadate(−I)

A matter of attraction: A magnet of nominal VII(TCNB−)1.5(TCNB0)x−1.5[V−I(CO)v]0.5⋅z solvent composition (Tc=325 K) is synthesized and its magnetic properties examined. Its amorphous nature makes it difficult to determine its complex composition and structure. It is a soft ferrimagnet with a coerciv...

Zusammenfassung:A matter of attraction: A magnet of nominal VII(TCNB−)1.5(TCNB0)x−1.5[V−I(CO)v]0.5⋅z solvent composition (Tc=325 K) is synthesized and its magnetic properties examined. Its amorphous nature makes it difficult to determine its complex composition and structure. It is a soft ferrimagnet with a coercive field of 7 Oe. The picture shows a sample in a capillary tube being attracted to a magnet at room temperature.
