The synthesis of [Bi2(biph)3] (5) and [PPN]-[BiCl2(biph)] (6) (biph = 2,2′-biphenylylene, PPN = Ph3P=N=PPh3), the first structurally characterized biphenylylene complexes of bismuth (III), are described. Complex 5 crystallizes as a THF (tetrahydrofuran) solvate; each bismuth is three-coordinate with a trigonal pyramidal geometry. The solid state of 6 comprises separated [PPN]+ cations and [BiCl2(biph)]- anions. The anion adopts a trigonal bipyramidal geometry at the bismuth; the axial sites are occupied by chloride ligands, and two of the three equatorial sites are occupied by ring carbon atoms.
