Graphical Abstract

Magnetic measurements on a {Dy4} 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 Ueff=170 K is the highest reported to date.
