Abstract: Abstract Reactions of (Cp 2 Ti) 2 AlH 4 Cl and (Cp 2 Ti) 2 AlH 4 BH 4 (Cp = η 5 -C 5 H 5 ) with LiCH 3 and LiAl(CH 3 ) 4 in ether or in an ether/benzene mixture yield a trinuclear complex Cp 2 Ti(μ 2 -H) 2 Al(CH 3 )(μ 2 -H) 2 TiCp 2 , which crystallizes in a rhombic lattice with unit cell parameters a 8.405(1), b 21.349(3), c 22.337(3) A, space group F2dd , Z = 8. The compound is unstable and decomposes in solution to give a new modification of a hexanuclear complex [Cp 2 Ti(μ 2 -H) 2 Al(μ 2 -H)(η 1 : η 5 -C 5 H 4 )TiCp(μ 2 -H)] 2 with ...
