Electronic structures of three cubane-type sulfur-bridged molybdenum clusters [Mo4S4(H2O)12]4+(1A), [Mo4S4(H2O)12]5+(1B), and [Mo4S4(H2O)12]6+(1C) have been calculated by the spin-polarized discrete-variational(DV)-Xα method. The calculations explain successfully the experimental results of valence-band X-ray photoelectron spectra, and magnetic measurements.
