Lithium aluminates Li[Al(O-2,6-Me2C6H3)R′3] (R′ = Et, Ph) react with the μ3-alkylidyne oxoderivative ligands [{Ti(η5-C5Me5)(μ-O)}3(μ3-CR)] [R = H (1), Me (2)] to afford the aluminum–lithium–titanium cubane complexes [{R′3Al(μ-O-2,6-Me2C6H3)Li}(μ3-O)3{Ti(η5-C5Me5)}3(μ3-CR)] [R = H, R′ = Et (5), Ph (7); R = Me, R′ = Et (6), Ph (8)]. Complex 7 evolves with the formation of a lithium dicubane species and a Li{Al(μ-O-2,6-Me2C6H3)Ph3}2] unit.
