Tris(4-methylbenzyl)(1,4,7-trimethyl-1,4,7-triazacyclononane)lanthanum(III)

The title compound, [La(C8H9)(3)(C9H21N3)], incorporating a fac-kappa N-3 ligand and formed by reaction of La(CH2C6H4-4-Me)(3) (THF)(3) (THF is tetrahydrofuran) and 1,4,7-trimethyl-1,4,7-triazacyclononane (Me-3-TACN), was synthesized in THF solution. In the crystal structure, the La atom is seven-coordinated by three N atoms from a TACN ligand and four C atoms from three benzyl ligands, one of which is bound eta(2).
