Reaction of bicine {BicH(3), N,N-bis(2-hydroxyethyl)glycine} with an Fe(III) oxo-centered pivalate triangle in MeCN in the presence of Et2NH yields [Et2NH2](2)[Fe6O2(OH)(2)(Bic)(2)(O2CCMe3)(8)], which possesses an S = 5 ground state.

Changing the base to NaOMe produces [Fe12O4(Bic)(4)(HBic)(4)(O2CCMe3)(8)], which contains two Fe-6 units bridged by the carboxylate arms from the bicine ligands. The complex displays strong antiferromagnetic coupling leading to an S = 0 ground state. (C) 2009 Elsevier Ltd. All rights reserved.
