Abstract Reactions of a m ‐terphenylhydridostannylene with β‐diketiminato magnesium and calcium hydrides provide bis‐μ 2 ‐hydrido species, the heterobimetallic constitutions of which are maintained after the addition of THF donor solvent. In both cases, reactions with hex‐1‐ene result in the formation of tetravalent organostannyl alkaline earth derivatives. Whereas the magnesium reagent undergoes facile twofold addition, the calcium‐centered process is arrested after a single alkene reduction event. This contrasting behavior is assessed to result from the heavier alkaline earth element's ability to form a persistent polyhapto interaction with an arene substituent of the m‐terphenyl ligand.
