The precursors[Fe(III)(L-SY)Cl] ((LH2)-L-SY) = N,N'-bis(1-hydroxy-Y-2-benzyliden)-1,6-diamino-3-thiohexane, (Y = H, 3EtO, 5Me) are high-spin (S = 5/2) complexes. The precursors are combined with [Fe(II)(CN)(6)](4-) and [Co(III)(CN)(6)](3-) to yield star-shaped heptanuclear clusters, [Fe(II)(CN-Fe(III)L-SY)(6)]Cl-2 and [Co(III)(CN-Fe(III)L-SY)(6)]Cl-3. The star-shaped compounds are high-spin (HS) systems at room temperature. On cooling to 20 K some of the iron(III) centers perform some HS-HS transition. (c) 2006 Elsevier Ltd. All rights reserved.
