| Abstract: | Reactions of the zinc(I) complex Zn2(Mesnacnac)2] (Mesnacnac=(2,4,6‐Me3C6H2)NC(Me)]2CH) with solid K3Bi2 dissolved in liquid ammonia yield crystals of the compound K4ZnBi2]?(NH3)12 ( 1 ), which contains the molecular, linear heteroatomic Bi? Zn? Bi]4? polyanion ( 1 a ). This anion represents the first example of a three‐atomic molecular ion of metal atoms being iso(valence)‐electronic to CO2 and being synthesized in solution. The analogy of the discrete Bi? Zn? Bi]4? anion and the polymeric  (ZnBi4/2)4?] unit to monomeric CO2 and polymeric SiS2 is rationalized. |
