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, β″-(BEDO-TTF)[Co(pdms)]·(MeCN)(HO) () (BEDO-TTF = bis(ethylenedioxy)tetrathiafulvalene and Hpdms = 1,2-bis(methanesulfonamido)benzene), which manifests both metallic conduction (electrical conductivity up to 1000 S cm at 12 K under 2.0 gigapascal pressure) and SMM behavior in the temperature range 12-26 K for the first time.
单分子磁体在分子水平上表现出磁双稳性，由于其高磁密度，使其在基于分子的自旋电子学领域具有广阔前景。将单分子磁体行为和导电性整合在一种化合物中十分罕见，因为这两种物理性质通常不在相同的温度范围内起作用，这进一步阻碍了它们在实际应用中的使用。在此，我们展示了一种有机-无机分子杂化物β″-(BEDO-TTF)[Co(pdms)]·(MeCN)(HO) （）（BEDO-TTF = 双(乙二氧基)四硫富瓦烯，Hpdms = 1,2-双(甲磺酰胺基)苯），该化合物首次在12至26 K的温度范围内同时表现出金属导电性（在2.0吉帕斯卡压力下，12 K时电导率高达1000 S cm）和单分子磁体行为。
