The synthesis and first structural characterization of the [K(18-crown-6)] bismolyl Bi (C Me Bi) contact ion pair (1) is presented. Notably, according to Natural Resonance Theory calculations, the Bi anion of 1 features two types of leading mesomeric structures with localized anionic charge and two lone pairs of electrons at the Bi center, as well as delocalized anionic charge in the π-conjugated C Bi ring. The lone pairs at Bi enable a unique bridging coordination mode of the bismolyl ligand, as shown for the first rare earth metal bismolyl complex (Cp Y) (μ-η -Bi ) (2).
