A well-defined two-step relaxation, described by the sum of two modified Debye functions, is observed in a new alkoxido-bridged linear tetranuclear DyIII aggregate showing single-molecule magnet behavior with remarkably large energy barrier. This compound represents model molecular clear relaxation evidenced frequency-dependent susceptibility, which therefore may stimulate further investigations regarding dynamics lanthanide-based systems.
