Abstract

Abstract : 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 ‐C20 H19 )2 Ti(μ‐H)]2 (2a ), and bis(η 5 ‐2‐adamantylcyclopentadienyl)‐titanium hydride dimer, [(η 5 ‐C15 H19 )2 Ti(μ‐H)]2 (2b ), are formed via activation of molecular hydrogen by the corresponding bis(η 5, η 1 ‐pentafulvene)titanium complexes1a and1b at ambient temperatures and pressures in high yields. The hydride complexes2a and2b exhibit planar [Ti2 H2 ] cores and, as a result of the heterolytic cleavage of molecular hydrogen, substituted Cp Ligands were formed during the reaction. Abstract :
