Synthesis, structure, and sup 31 P NMR spectra of Mo sub 2 W sub 2 Cl sub 8 (PR sub 3 ) sub 4 rectangular clusters

The new compounds Mo{sub 2}W{sub 2}Cl{sub 8}(PMe{sub 3}){sub 4}{center dot}{sub 4}H{sub 8}O (I) and Mo{sub 2}W{sub 2}Cl{sub 8} (P(n-Bu){sub 3}){sub 4} (II) have been prepared by cycloaddition reactions of MoW(O{sub 2}CCMe{sub 3}){sub 4}. Yellow-green crystals of I provided crystallographic data for...
