Abstract

The compound Me₂In(C₅H₅) has been prepared by a metathetical reaction between Me₂InCl and Li(C₅H₅) in THF solution and by a methane elimination reaction between InMe₃ and C₅H₆ at 145-160°C in a sealed tube and fully characterized. An X-ray structural study identified an infinite linear polymer with cyclopentadienide units bridging InMe₂ moieties through the 1 and 3 positions of the ring. Bridging is sufficiently strong to prevent melting before thermal decomposition at 195-200°C and to make the compound insoluble in all solvents except those that are good Lewis bases such as THF. The compound exists in THF solution as an equilibrium mixture of Me₂In(C₅H₅)·THF, MeIn(C₅H₅)₂· THF, and InMe₃·THF according to its ¹H NMR spectrum.
