The first Te–Mn–CO clusters were obtained by the thermal reaction of K 2 TeO 3 with [Mn 2 (CO) 10 ] in MeOH. The basicity of the μ 4 ‐Te ligand in the octahedral cluster anion [( μ 4 ‐Te) 2 Mn 4 (CO) 12 ] 2− is demonstrated by its binding to the fragment [(TeMe 2 )Mn(CO) 4 ] + in an axial fashion to afford the novel cluster 1 .
