Discovery of the 12‐electron clusters 1 and 2 has afforded insights into the complementary bonding in clusters of early and late transition metals with alkoxide and carbonyl ligands, respectively. In 1 , a WCl(O i Pr) unit caps a triangular W 3 fragment; similarly, in cluster 3 , PtL 2 caps an Os 3 triangle. Compared with the d 10 PtL 2 fragment, however, the d 4 WCl(O i Pr) unit is a stronger electron acceptor. This leads to marked changes in the MM bond in the alkoxide/carbonyl clusters of the early/late transition metals.
