Triple Halide Bridges in Chiral MnII2MnIII6NaI2 Cages: Structural and Magnetic Characterization.

A family of decanuclear chiral clusters with a MnII2MnIII6NaI2 core have been synthesized from enantiomerically pure Schiff bases. The new systems consist of two MnIIMnIII3NaI units linked by rare triple chloro or bromo bridges between the divalent Mn cations. Susceptibility measurements point out the weak antiferromagnetic interaction mediated by these kinds of bridges and afford the first magnetic measurements for the (μ-Br)3 case.
