Metal carbonyl C=O bond strength varies systematically according to the metal center, its oxidation state, and its backbonding capabilities.

The analysis

The retrieved papers provide theoretical and experimental evidence demonstrating that C=O bond strengths and stretching frequencies vary systematically in metal carbonyl complexes as a function of electronic structure, periodic trends, and metal-ligand backdonation.
