The reaction of Pr(AlMe(4))(3) with 1,3,5-trimethyl-1,3,5-triazacyclohexane (TMTAC) leads to the formation of two isomeric products by C-H activation of the AlMe(4)(-) ligands: [(eta(3)-TMTAC)Preta(4)-(Me(3)AlCH(2)AlMe(2)CH(2)AlMe(3))}] (1), containing a linear tris(aluminate) trianion, and [(eta(3)-TMTAC)Pr(eta(4)-CH(AlMe(3))(3)})] (2), containing a branched tris(aluminate) trianion.
