The triangular clusters [Zn3Cp*3](+) and [Zn2CuCp* 3] were obtained by addition of the in situ generated, electrophilic, and isolobal species [ZnCp*](+) and [CuCp*] to Carmona I s compound, [Cp*Zn-ZnCp*], without splitting the Zn-Zn 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 saromaticity similar to the triatomic hydrogen ion [H3](+). The new species serve as molecular building units of CunZnm nanobrass clusters as indicated by LIFDI mass spectrometry.
