Abstract

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)6Br4(py)4]·2Et2O·MeOH (1·2Et2O·MeOH), [Fe8O2(OMe)3.85(N3)4.15(Me-sao)6(py)2] (2), [Fe6O2(O2CPh-4-NO2)4(Me-sao)2(OMe)4Cl2(py)2] (3), [Fe6O2(O2CPh-4-NO2)4(Et-sao)2(OMe)4Cl2(py)2]·2Et2O·MeOH (4·2Et2O·MeOH), [HNEt3]2[Fe6O2(Me-sao)4(SO4)2(OMe)4(MeOH)2] (5) and [HNEt3]2[Fe6O2(Et-sao)4(SO4)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.
