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 K4[ZnBi2]⋅(NH3)12 (1), which contains the molecular, linear heteroatomic [BiZnBi]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 [BiZnBi]4− anion and the polymeric [(ZnBi4/2)4−] unit to monomeric CO2 and polymeric SiS2 is rationalized.
