The magnetic and X-ray photoelectron spectroscopy (XPS) studies on the transition metal substituted, dimeric polyoxotungstate [Fe4(H2O)10(β-SbW9O33)2]6- are reported. The magnetic data were analysed by using an isotropic Heisenberg Hamiltonian. The ground state of the frustrated molecule has a total spin of S = 2. The XPS Fe 2p spectra suggest a 2+ formal valence state. The deviation from the contained Fe3+ ions can be explained by charge-transfer e®ects.
Keywords: magnetic molecules; polyoxotungstates; Heisenberg model; magnetization measurements; x-ray photoelectron spectroscopy
