摘要：

Thiirane (2) is used as source for the directed formation of the symmetrically bridged complex {(eta5-C5H5)(CO)2Mn}2S (3) by its reaction with (eta5-C5H5)(CO)2 MnTHF (1). Compound 3 can be oxidized, protonated, or methylated to give the SO complex {(eta5-C5H5)(CO)2Mn}2SO (4) or the SR+ cations (CO)2Mn}2SR]+ (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 3 crystallizes in the triclinic space group P1Bar and shows the open form IIa with 3c4e bonding system which is isolobal to SO2, whereas the analogous rhenium complex has the isomeric closed form IIb with a metal-metal bond which is isolobal to thiirane.
