Relativistic electrons, delocalization

The ligand CN forms bonds with transition-metal atoms that are very covalent in nature, resulting in strong electronic delocalization. Added to this, the presence of a relativistic atom induces complex and interesting effects. The low-spin complex ion [Ir(CN)s]3-, in which Ir is in the unusual formal oxidation state +2, has been obtained by irradiation of the hexacoordinated diamagnetic Ir(+3) complex with electrons or X-rays in solid alkali halide matrices [98]. [Ir(CN)5]3 has a square-pyramidal structure (see Fig. 9) and one unpaired electron in the HOMO. [Pg.85]
