The synthesis and crystal structures of two dinuclear titanocene hydride complexes are reported. Both complexes, namely bis(η 5 ‐(di‐ para ‐tolylmethyl)cyclopentadienyl)titanium hydride dimer, [(η 5 ‐C 20 H 19 ) 2 Ti(μ‐H)] 2 ( 2a ), and bis(η 5 ‐2‐adamantylcyclopentadienyl)‐titanium hydride dimer, [(η 5 ‐C 15 H 19 ) 2 Ti(μ‐H)] 2 ( 2b ), are formed via activation of molecular hydrogen by the corresponding bis(η 5 ,η 1 ‐pentafulvene)titanium complexes 1a and 1b at ambient temperatures and pressures in high yields. The hydride complexes 2a and 2b exhibit planar [Ti 2 H 2 ] cores and, as a result of the heterolytic cleavage of molecular hydrogen, substituted Cp Ligands were formed during the reaction.
