Triple Halide Bridges in Chiral (Mn2Mn6Na2I)-Mn-II-Na-III Cages: Structural and Magnetic Characterization

A family of decanuclear chiral clusters with a (Mn2Mn6Na2I)-Mn-II-Na-III core have been synthesized from enantiomerically pure Schiff bases. The new systems consist of two (Mn2Mn6Na2I)-Mn-II-Na-III units linked by rare triple chloro or bromo bridges between the divalent Mn cations. Susceptibility me...

Resumo:A family of decanuclear chiral clusters with a (Mn2Mn6Na2I)-Mn-II-Na-III core have been synthesized from enantiomerically pure Schiff bases. The new systems consist of two (Mn2Mn6Na2I)-Mn-II-Na-III units linked by rare triple chloro or bromo bridges between the divalent Mn cations. Susceptibility measurements point out the weak anti ferromagnetic interaction mediated by these kinds of bridges and afford the first magnetic measurements for the (mu-Br)(3) case.
