Abstrakt: A synthetic protocol was developed for a series of cubane-type [Mo 3 S 4 M] clusters that incorporate halides of first-row transition metals (M) from Groups 4-10. This protocol is based on the anionic cluster platform [Cp* 3 Mo 3 S 4 ] - ([1] - ; Cp*=η 5 -C 5 Me 5 ), which crystallizes when K(18-crown-6) is used as the counter cation. Treatment of in situ-generated [1] - with such transition-metal halides led to the formation of [Mo 3 S 4 M] clusters, in which the M/halide ratio gradually changes from 1:2 to 1:1.5 and to 1:1, when moving from early to late transition metals. This trend suggests a tendency for early transition metals to tolerate higher oxidation states and adopt larger ionic radii relative to late transition metals. The properties of the [Mo 3 S 4 Fe] cluster 6 a were investigated in detail by using 57 Fe Mössbauer spectroscopy and computational methods.
