Coordination Chemistry of rr‐Bonded Cyclopentadienyl Chalcogeno Ethers, I. ‐ Chelate Complexes of Pentakis(methylthio)cymantrene with Metal Carbonyls [C 5 (SMe) 5 ]Mn(CO) 3 (1) reacts with W(CO) 5 (THF), Mo(CO) 4 (πC 7 H 8 ), Cr(CO) 3 (NCMe) 3 , and Re(CO) 4 (π‐C3H5)/HBF 4 to yield the monochelate complexes [[C 5 (SMe) 5 ]Mn(C0) 3 ][M(CO) 4 ] (M = W: 2; M = Mo: 3) and the dichelate complexes [[C 5 (SMe) 5 ]Mn(CO) 3 ][M(C0) 4 ] 2 (M = W: 4; M = Cr: 5; M = Re⊕ BFF 4 ⊖ : 6). The reaction with Mo(CO) 3 (p‐xylene) in THF leads via unstable intermediates, which contain coordinated THF, to a mixture of 3 and [[C 5 (SMe) 5 ]Mn(CO) 3 ][Mo(CO) 4 ] 2 (7). The structures of 3 and 4 in the crystal have been determined by X‐ray diffraction methods.
