Abstract

The synthesis of [Bi-2(biph)(3)] (5) and [PPN]-[BiCl2(biph)] (6) (biph=2,2'-biphenylylene, PPN=Ph(3)P=N=PPh(3)), 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 tree equatorial sites are occupied by ring carbon atoms.
