Abstract

Under solvothermal conditions the unprecedented nonanuclear FeIII aggregate [Fe93-O)4(μ-OH)4(hpdta)4]5− is formed through the formal encapsulation of [Fe(H2O)6]3+ by four [Fe2(hpdta)(H2O)2]+ units: the aggregates have ground state spins of S = 13/2 while the observed hysteresis below 1.8 K results from inter-cluster antiferromagnetic coupling.
