Abstract

Five Mn3Zn2 heterometallic complexes have been synthesized and structurally and magnetically characterized. Spin ground states up to S = 6 have been observed for these complexes and are shown to depend on the cocrystallizing cation and on the terminal ligand. Large axial zero-field interactions (D = -1.16 K) are the result of near-parallel alignment of the Mn-III Jahn-Teller axes. High-frequency electron paramagnetic resonance, single-crystal magnetization hysteresis, and alternating current susceptibility measurements are presented to characterize [NEt4](3)[Mn3Zn2(salox)(3)O(N-3)(6)X-2] [X- = Cl- (1), Br- (2)] and [AsPh4)(3)[Mn3Zn2(salox)(3)O(N-3)(6)Cl-2] (3) and reveal that 1 and 2 are single-molecule magnets (U-eff = 44 K), while 3 is riot.
