title: Bis(pentalene)di-titanium: a bent double-sandwich complex with a very short Ti-Ti bond.
abstract: The novel bimetallic bis(pentalene) complex Ti2(μ:η(5),η(5)-Pn(†))2 (Pn(†) = C8H4{Si(i)Pr3-1,4}2) has been synthesised and structurally characterised. Structural data show a Ti-Ti distance of 2.399(2) Å, consistent with a strong metal-metal interaction, which DFT calculations best describe as a double bond with σ and π components.
