Bifunctional electrically conducting single‐molecule magnets are highly promising platforms for non‐volatile memory devices and quantum computing applications. The development of these molecular materials, however, has largely been hindered by the lack of straightforward synthetic methods. Herein a facile and modular approach is demonstrated for the realization of bifunctional materials that does not require electrochemical or chemical oxidation to obtain partially charged organic radicals. Magnetic and electrical conductivity studies reveal that the Dy III compound exhibits slow relaxation of the magnetization between 5.0–8.0 K and semiconducting behavior over the range 180–350 K. DC magnetic fields have been found to suppress the quantum tunneling of the magnetization and affect the spin‐canted antiferromagnetic interactions.
