Magnetic measurements on a {Dy 4 } single‐molecule magnet (SMM) with a defect‐dicubane central core, synthesized using 1,2‐bis(2‐hydroxy‐3‐methoxybenzylidene) hydrazone and 3‐methoxysalicylaldehyde hydrazone as chelating agents (see structure; yellow Dy, red O, blue N, green Cl), confirm SMM behavior and reveal hysteresis loops at 7 K. The anisotropic energy barrier of U eff =170 K is the highest reported to date.
