Abstract

The synthesis, structure and magnetic properties of an octametallic iron(III) ring is reported. Alternate edges of the ring are bridged by a hydroxide and two pivalates, or by one pivalate and two phenoxides. By addition of biphenol to the reaction a hexadecametallic iron(III) cage can be made where the 16 metals are arranged in two linked {Fe8} rings. The rings are staggered with respect to one another, and lie on the vertices of an octagonal anti-prism. Magnetic studies on the octametallic ring allows exchange parameters to be obtained. Similar studies on the {Fe16} barrel shows the exchange interactions within the rings to be similar, with a significant paramagnetic impurity present. © 2013 Elsevier Ltd. All rights reserved.
