Heterometallic iron carbonyl chalcogenide clusters containing ruthenium, rhenium, manganese, and molybdenum

The reactions of Fe2Se2(CO)6 (1b) with Ru(CO)4(C2H4), Mn2(CO)10, or Np"Re(CO)2THF gave the known cluster Fe2RuSe2(CO)9 (4b) and new clusters (CO)6Fe2Se2Mn2(CO)8 (5) and Cp"Re(CO)2Se2Fe2(CO)6 (6). By successive reactions of Mo(CO)5THF with 1b and Fe2Te2(CO)6, the new heterometallic heterochalcogenide cluster Fe2(CO)6(μ3-Se)2Mo(CO)2(μ3-Te)2Fe2(CO)6 (8) was synthesized. The structures of 4b, 5, and 6 were determined by X-ray diffraction analysis.
