Abstract
Variable-temperature magnetic susceptibility measurements performed on two hexairon(III) clusters containing a mu6-oxo bridge show that this unusual bridging mode leads to weak antiferromagnetic exchange-coupli ng interactions between the metal centers, with J(trans) and J(cis) va lues of 19(2) and 9(1) cm-1, respectively. The result is relevant to t he search for magneto-structural correlations in oxo-bridged polyiron aggregates.
