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

The title compound, [La(C 8 H 9 ) 3 (C 9 H 21 N 3 )], incorporating a fac ‐κ 3 N ligand and formed by reaction of La(CH 2 C 6 H 4 ‐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 η 2 .
