substituents, while in the silylated derivative 4, the E-anti:E-anti form is present in the solid-state. Synthesis of the bimetallic aluminium compounds 1,4-C6H4[CNiPr}2AlMeX]2 (5, X=Cl; 6, X=Me) was achieved from AlMe2Cl using 2 by either the direct protonolysis of an AlCbond (5), or the trans-metallation reaction of the in situ generated dilithio-salt (6). Structural characterisation of 6 revealed a monomeric
