The triangular clusters [Zn 3 Cp* 3 ] + and [Zn 2 CuCp* 3 ] were obtained by addition of the in situ generated, electrophilic, and isolobal species [ZnCp*] + and [CuCp*] to Carmona’s compound, [Cp*ZnZnCp*], without splitting the ZnZn bond. The choice of non‐coordinating fluoroaromatic solvents was crucial. The bonding situations of the all‐hydrocarbon‐ligand‐protected clusters were investigated by quantum chemical calculations revealing a high degree of σ‐aromaticity similar to the triatomic hydrogen ion [H 3 ] + . The new species serve as molecular building units of Cu n Zn m nanobrass clusters as indicated by LIFDI mass spectrometry.
