    • ave ≈ 0°) that allows for a better aim separation, thereby facilitating the description of the bonding scheme. However, we also show that the twist between the hydrazonato ligands observed in isomers M-IIa and M-IIc (M = Th, U, Zr) does not affect the overall metal-ligand interactions in these complexes.
