  The mu(2)-imide complexes [Ln(AlMe4)(mu(2)-Nmes*)](x) (mes* = C(6)H(2)tBu(3)-2,4,6) (Ln = Y, La, Nd, Lu) are synthesized from homoleptic heterobimetallic complexes Ln(AlMe4)(3) utilizing two distinct protocols: reaction with 2,4,6-tri-tert-butylaniline in hexane via methane elimination or with potassium (2,4,6-tri-tert-butylphenyl)amide in toluene according to a salt metathesis-protonolysis tandem reaction. Complexes [Ln(AlMe4)(mu(2)-Nmes*)](2) (Ln = Y, Nd, Lu) revealed isomorphous solid-state structures, featuring an asymmetrically bridged Ln(2)N(2) core with very short Ln-N distances (2.071(1)-2.155(3) angstrom). In the solid-state structure of the lanthanum derivative similar dimeric subunits assemble as La4Al4 oligomers through mu(2)-eta(1):eta(2)-bridging tetramethylaluminato moieties. [La(AlMe4)(mu(2)-Nmes*)](4) displays La-arene interactions (2.702(6) angstrom) that are considerably shorter than the La(mu-CH3)(aluminato) bond lengths.
