Cothermolysis of the clusters [Fe-3(mu(3)-Q)(mu(3)-AsCH3)(CO)(9)] (Q = Se and Te) and the complexes [Cp*M(CO)(2)] (M = Rh and Ir) was accompanied by isolobal replacement of the fragment {Fe(CO)(3)} by {Cp*M}; the final reaction products were [Fe2M(mu(3)-Q)(mu(3)-AsCH3)(CO)(6)Cp*]. For M = Ir, these reactions involved addition of an iridium fragment to the starting cluster to give the intermediate adducts [Fe3Ir(mu(4)-Q)(mu(4)-AsCH3)(CO)(8)Cp*]. In the case of [Cp*Rh(CO)(2)], the intermediate tetranuclear rhodium adducts were also isolated. Sets of these adducts differed for the selenide ([Fe3Rh(mu(4)-Se)(mu(4)-AsMe)(CO)(8)Cp*] and [Fe2Rh2(mu(3)-Se)(mu(4)-AsMe)(CO)(6)Cp-2*]) and telluride clusters ([Fe3Rh(mu(4)-Te)(mu(3)-AsMe)(mu-CO)(CO)(9)Cp] and [Fe3Rh2(mu(3)-Te)(mu(4)-AsMe)(mu(3)-CO)(mu-CO)(CO)(8)Cp-2*]). The structures of all 10 novel heterometallic clusters were determined by single-crystal X-ray diffraction analysis.
