Title

Single-Molecule-Magnet Behavior And Spin Changes Affected By Crystal Packing Effects

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 MnIII 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)3O(N 3)6X2] [X- = Cl- (1), Br- (2)] and [AsPh4]3[Mn3Zn 2-(salox)3O(N3)6Cl2] (3) and reveal that 1 and 2 are single-molecule magnets (Ueff = 44 K), while 3 is not. © 2008 American Chemical Society.
