✦ Synopsis

Sulfur bridge / Bonding system, 3c4e / Sulfanylium cations / Manganese complexes Thiirane as Sulfur Source for the 3c4e Bonding System in the Complex {(q5-C5H5)(CO),Mn},S Thiirane (2) is used as source for the directed formation of the symmetrically bridged complex {(q5-C5Hs)(CO)zMn}zS (3) by its reaction with (q5-C5H5)(CO)ZMnTHF (1). Compound 3 can be oxidized, protonated, or methylated to give the SO complex {(q5-C5H5)(CO),Mn),S0 (4) or the SR+ cations [{(q5-C5H5)-(CO)zMn}zSR]+ (R = H, CH3) (5,6). Compounds 5 and 6 show an equilibrium between the open and closed form in solution at room temperature. According to an X-ray structural analysis
