WebJan 7, 2024 · REACTIONS OF METAL CARBONYLS• Substitution Reactions • Many substitution reactions occur between metal carbonyls and other potential ligands. • For example, • Cr(CO)6 + 2 py → Cr(CO)4(py)2 + 2 CO • Ni(CO)4 + 4 PF3 → Ni(PF3)4 + 4 CO • Mo(CO)6 + 3 py → Mo(CO)3(py)3 + 3 CO WebThe bonding in nonclassical carbonyl complexes, those with unusually high CO stretching frequencies, is analyzed via Fenske-Hall molecular orbital calculations. The systems analyzed include nonclassical carbonyl complexes of d10 Ag(I) and of d0 Zr(IV); these are compared to classical carbonyl complexes of Zr(II) and Mo(O). The Cotton-Kraihanzel …
