The syntheses, structures and magnetic properties of six iron complexes stabilised with the derivatised salicylaldoxime ligands Me-saoH2 (2-hydroxyethanone oxime) and Et-saoH2 (2-hydroxypropiophenone oxime) are discussed. The four hexanuclear and two octanuclear complexes of formulae [Fe8O2(OMe)4(Me-sao)6Br 4(py)4]·2Et2O·MeOH (1·2Et2O·MeOH), [Fe8O2(OMe) 3.85(N3)4.15(Me-sao)6(py) 2] (2), [Fe6O2(O2CPh-4-NO 2)4(Me-sao)2(OMe)4Cl 2(py)2] (3), [Fe6O2(O 2CPh-4-NO2)4(Et-sao)2(OMe) 4Cl2(py)2]·2Et2O·MeOH (4·2Et2O·MeOH), [HNEt3]2[Fe 6O2(Me-sao)4(SO4) 2(OMe)4(MeOH)2] (5) and [HNEt3] 2[Fe6O2(Et-sao)4(SO 4)2(OMe)4(MeOH)2] (6) all are built from a series of edge-sharing [Fe4(μ4-O)]10+ tetrahedra. Complexes 1 and 2 display a new μ4-coordination mode of the oxime ligand and join a small group of Fe-phenolic oxime complexes with nuclearity greater than six. The Royal Society of Chemistry 2011.
