Popis: | A heterobinuclear transition metal complex with a Ta−Ir multiple bond, Cp*(Me3SiCH2)2Ta−IrCp*(H)2 (1), was synthesized using a salt elimination reaction. The isolable complex was characterized by NMR, IR, UV−vis spectroscopy, and X-ray crystallography. Compound 1 features an exceptionally short intermetallic distance (Ta−Ir 2.4457(3) Å). DFT calculation for 1 revealed the presence of a highly covalent bonding nature in spite of the involvement of such disparate d elements. Oxidative additions of C−H, N−H, and O−H bonds to 1 were also investigated. |
