Heterobimetallic µ2-imide complexes [Ho(µ2-Nmes*){Al(CH3)4}]2 (1, supermesityl = mes* = C6H2tBu3-2,4,6) and [Ho(µ2-Nmes*){Ga(CH3)4}]2 (2) have been synthesized from homoleptic complexes Ho[M(CH3)4]3 (M = Al, Ga) via deprotonation of H2Nmes* or with K[NH(mes*)] according to a salt metathesis-protonolysis tandem reaction. Single-crystal X-ray diffraction of isostructural complexes [Ho(µ2-Nmes*){M(CH3)4}]2 (M = Al, Ga) revealed asymmetric Ho2N2 metallacycles with very short Ho–N bond lengths and secondary Ho arene interactions.
