Neutral Group 13 combinations with the Saltren ligand (tris(((2-hydroxybenzyl)amino)ethyl)amine)) have been prepared and their reactivity explored. The majority of the compounds are of formula Saltren(MR2)3 where M = B; R = OMe (1), OEt (2), OnPr (3); M = Al; R = Me (4), Et (5), iBu (6) and R = Et for M = Ga (7) and In (8). Mono-, [SaltrenHAlMe]n (9), and tetra-metallic, Saltren(AlMe2)3-AlMe3 form when one and four equivalents of AlMe3 are added to the ligand. Compound 9 can be converted to 4 by the addition of two or three additional molecules of AlMe3. Compounds 1 and 4 form unique zwitterionic compounds, [SaltrenH3{M(OSiPh3)3}3] (M = B (11) and Al (12) when combined with six equivalents of Ph3SiOH. Attempts to prepare those of formula Saltren {MR(OSiPh3)}3 where M = B and Al led to an inseparable mixture of compounds. All of the compounds were characterized by standard techniques and, in the case of 1, 4, 7 and 12, by X-ray crystallography.
