abstract = {A new heptanuclear iron(III) oxide pivalate cluster
[Fe7O4(OH)(2)(O2CCMe3)(11)(bpm)(2)(H2O)] (1) (bpm =
2,2'-bipyrimidine) has been prepared and characterized. 1
features an asymmetric {Fe7O6} framework based on two
corner-sharing {Fe-4(mu(3)-O)(2)} groups, themselves
comprising {Fe-3(mu(3)-O)} motifs that are formally retained
from the {Fe6O4} precursor used in thesynthesis of 1.
Compared to existing Fe-III oxide carboxylate clusters, the
{Fe7O6} fragment in 1 exhibits an unusually high Fe:O ratio,
with all seven oxygen sites efficiently mediating magnetic
exchange. Correspondingly, 1 shows strong intramolecular
antiferromagnetic coupling.},
