Abstract

[Sm(TpMe,Me)2] reacts with dichalcogenides to give a series of isoleptic complexes [Sm(TpMe,Me)2ER] (E = O, S, Se, Te; R = phenyl) which have been structurally characterized. An unusual distortion of the TpMe,Me for the selenolates is discussed in relation to fluxionality and decomposition mechanisms for these complexes. The fluxional behaviour of [Sm(TpMe,Me)2(S2CNR2)] and [Sm(TpMe,Me)2(S-2-pyr)] is also described. [Sm(TpMe,Me)2] reacts with Mn2(CO)10 to give [Sm(TpMe,Me)2]Mn(CO)5 and small amounts of {[Sm(TpMe,Me)2]2(μ-O 2CH)}Mn(CO)5 - effectively the room temperature conversion of CO to formate. The corresponding reaction with Re2(CO)10 yields [Sm(TpMe,Me)2]Re(CO)5 and [Sm(TpMe,Me)2]2Re4(CO)17. © 2000 Elsevier Science S.A. All rights reserved.
