【 摘 要 】

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 Hoarene interactions.
