Structural, Spectroscopic, Electrochemical, and Magnetic Properties for Manganese(II) Triazamacrocyclic Complexes.

ABSTRACT: We report the synthesis of [Mn(tacud)₂](OTf)₂ (1) (tacud = 1,4,8-triazacycloundecane), [Mn(tacd)₂](OTf)₂ (2) (tacd = 1,4,7-triazacyclodecane), and [Mn(tacn)₂](OTf)₂ (3) (tacn = 1,4,7-triazacyclononane). Electrochemical measurements on the Mn^III/II redox couple show that complex 1 has the largest anodic potential of the set (E _1/2 = 1.16 V vs NHE, ΔE _p = 106 mV) compared to 2 (E _1/2 = 0.95 V, ΔE _p = 108 mV) and 3 (E _1/2 = 0.93 V, ΔE _p = 96 mV). This is due to the fact that 1 has the fewest 5-membered chelate rings and thus is least stabilized. Magnetic studies
