## Abstract We present the synthesis and characterization of the firsttrisilaโbridged __ansa__ halfโsandwich complexes of Group 6 transition metals in a oneโstep synthesis from dilithiatedprecursors Li[M(ฮท^5^โC~5~H~4~Li)(CO)~3~] (M = W, Mo) by use ofstoichiometric amounts of Si~3~Me~6~Cl~2~ under d
