The cross‐transfer of Te and CO ligands from one metal centre to the other in the system [CpNb(Te 2 H)]/[Co 2 (CO) 8 ] (Cp # =C 5 Me 5 (Cp*), C 5 Me 4 Et (Cp × )) leads to the stepwise formation of metal‐centered telluride clusters [Co 9 Te 6 (CO) 8 ] 2− ([ 1 ] 2− ) and [Co 11 Te 7 (CO) 10 ] n − ( n =2: [ 2 ] 2− , n =1: [ 3 ] − ) via the neutral niobocene derivative shown. The counterions in 1‐3 are all [CpNb(CO) 2 ] + cations. Electrochemical studies and DFT calculations provide evidence for three‐electron transfer steps within the [Co 11 Te 7 (CO) 10 ] n − ( n =0‐3) series.
