Abstract

Despite their inherent steric bulk, a combination of 2-hydroxy-1-naphthaldoxime (L1H2) with polyphenolic carboxylate ligands (1-Naphthoate, 9-Anthracene carboxylate) aid the construction and stabilisation of hexanuclear arrays of Fe(III) ions in the form of [Fe(III)(6)O-2(L-1)(2)(O2C-R)(10)(H2O)(2)]center dot 8MeCN (R = Naphth-(C10H8) (1); R = Anthra-(C14H9) (2)). Likewise, the sterically hindered ligand 3,5-di-tertbutyl-salicylaldoxime (L2H2) is able to aid the self-assembly of the tetranuclear, cubane-like species [Fe(III)(4)(L-2)(4)(MeOH)(4)(Cl)(4)] (3). Magnetic susceptibility studies carried out on 1 and 3 reveal antiferromagnetic exchange between the Fe(III) metal centres affording S = 0 ground spin states in both cases. (C) 2014 Elsevier B.V.
