4f-orbital covalency enables a single-crystal-to-single-crystal ring-opening isomerization in a CeIV-cyclopropenyl complex
{{output}}
Metal-ligand bonding interactions for f-element compounds are typically highly polarized with only minor covalent character. Whereas the 5d/6d orbitals are known to be chemically accessible for dative bonding, recent quantum chemical and spectroscopic analyses... ...
