The reactions between K5Bi4, [(C6H6)Cr(CO)(3)] or [(C7H8)Mo(CO)(3)], and [2.2.2]crypt in liquid ammonia yielded the compounds [K([2.2.2]crypt)](3)((3)-Bi-3)M(CO)(3)10NH(3) (M = Cr, Mo), which crystallize isostructurally in P2(1)/n. Both contain an 18 valence electron piano-stool complex with a (3)-coordinated Bi-3-ring ligand. The Bi-Bi distances range from 2.9560(5) to 2.9867(3) angstrom and are slightly shorter than known Bi-Bi single bonds but longer than Bi-Bi double bonds. The newly found compounds complete the family of similar complexes with E-3-ring ligands (E = P-Bi).
