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

The reactions of Fe2Se2(CO)(6)(1b) with Ru(CO)(4)(C2H4), Mn-2(CO)(10), or Cp'Re(CO)(2)THF gave the known cluster Fe2RuSe2(CO)(9) (4b) and new clusters (CO)(6)Fe2Se2Mn2(CO)(8) (5) and Cp'Re(CO)(2)Se2Fe2(CO)(6) (6). By successive reactions of Mo(CO)(5)THF with 1b and Fe2Te2(CO)(6), the new heterometallic heterochalcogenide cluster Fe-2(CO)(6)(mu(3)- Se)(2)Mo(CO)(2)(mu(3)-Te)(2)Fe-2(CO)(6) (8) was synthesized. The structures of 4b, 5, and 6 were determined by X-ray diffraction analysis.
