- Redox reactions of K₅Bi₄ and CpCo(CO)₂/Rh(CO)₂(acac) (acac = acetylacetonate) in ethylenediamine (en) yielded the first Bi₇³⁻ adducts [Bi₇M₃(CO)₃]²⁻ (M = Co, 1a; Rh, 2a) that have a new architype 10-vertex deltahedral structure, resulting from the unprecedented polycyclic η⁵-coordination addition reaction of the Bi₇³⁻ cage and three MCO⁺ fragments.
