The first group 15/16 cationic metal complex [Fe-2(Sb2S6)(CO)(6)][SbF6
](2) . 2SO(2) is formed when [S-8][Sb2F11](2) is reacted with 3 equiv
of iron pentacarbonyl in liquid sulfur dioxide at room temperature. Th
e cationic cluster is formed from an Sb2S6 cage capped on each end thr
ough eta(1)-S, eta(2)-S-2 bound Fe(CO)(3) units. There is a center of
inversion at the centroid position of the Sb2S6 cage. The antimony sou
rce is apparently the starting anion [Sb2F11](-). This appears to be a
n unprecedented example of the reaction of a cation with [Sb2F11](-).
