The coordination preferences of the ketiminato ligands L1H, [[RN(H)(C(Me))2C(Me)=O], R = 2,6-diisopropylphenyl (Dipp) or 2,6-dimethylphenyl (Dmp)} and L2H ([RN(H)C(Me)CHC(Me)=O], R = C 2H4NEt2) with group 13 elements were investigated. The expected N,O-chelated products [DmPL1BF 2] (1), [L2Al(Me)Cl] (2A and 2B), and [L 2InMe2] (6), were obtained from reactions with BF 3·OEt2, AlMe2Cl and InMe3 respectively, but the reaction of DippL1 with. GaCl3 afforded a metal-halide, neutral ligand adduct, [GaCl3· DippL1H] (3). More interestingly the reactions of DippL1 with InMe3, formed in situ from InCl3 and MeLi, led to the isolation of two ketiminate-supported LiCl cages [InMe2Li 7Cl5(DippL1-)2(DippL 1(THF)3] (4) and [Li5(Cl)-(DippL 1)4]·2PhMe (5). The lithium cage 4 features reaction of InMe3 with one backbone methyl group from each of two DippL1 ligands, to afford a tetraalkylindate moiety in the framework of two doubly deprotonated ligands (L-).
