The monoallenylidene complex [Cp(2)Mo(2)(CO)(4){mu-sigma:eta(2)-C=C-C(
Fc)(H)}] (5) and the diallenylidene complex Cp(2)Mo(2)(CO)(4)(mu-sigma
:eta(2)-C=C=C(H))}(2)Fc] (6) have been obtained from the corresponding
monocarbenium ion Mo(2)(CO)(4){mu-eta(2):eta(3)-HC=C-C(H)(Fc)}][BF4]
(3) and the dicarbenium ion CO)(4)(mu-eta(2):eta(3)-HC=C-C(H)}(2)Fc][(
BF4)(2)] (4) respectively, and their spectroscopic data are determined
.
