Emergence of Metallic Conduction and Cobalt(II)-Based Single-Molecule Magnetism in the Same Temperature Range

Single-molecule magnets exhibit magnetic bistabililties at the molecular level, making them promising for molecule-based spintronics due to high magnetic densities. The incorporation of SMM behavior and electrical conductivity in one compound is rare because these two physical properties often do not operate in the same temperature range, which further hinders their use in practical applications. Here we present an organic-inorganic molecular hybrid, beta ''-(BEDO-TTF)(3)[Co(pdms)(2)]center dot(MeCN)(H2O) (2) (BO3) (BEDO-TTF = bis(ethylenedioxy)tetrathiafulvalene and H(2)pdms = 1,2-bis(methanesulfonamido)benzene), which manifests both metallic conduction (electrical conductivity up to 1000 S cm(-1) at 12 K under 2.0 gigapascal pressure) and SMM behavior in the temperature range 12-26 K for the first time.
