Pentavalent actinyl nitrate complexes AnVO2(NO3)2- were produced by elimination of two NO2 from AnIII(NO3)4- for An = Pu, Am, Cm, Bk, and Cf. Density functional theory (B3LYP) and relativistic multireference (CASPT2) calculations confirmed the AnO2(NO3)2- as AnVO2+ actinyl moieties coordinated by nitrates. Computations of alternative AnIIIO2(NO3)2- and AnIVO2(NO3)2- revealed significantly higher energies. Previous computations for bare AnO2+ indicated AnVO2+ for An = Pu, Am, Cf, and Bk, but…

Activation of Water by Pentavalent Actinide Dioxide Cations: Characteristic Curium Revealed by a Reactivity Turn after Americium.
TLDR
It was found that AmO2- does not oxo-exchange, whereas CmO2+ does, establishing a "turn" to increasing the reactivity from americyl to curyl, which validates computational predictions.
The duality of electron localization and covalency in lanthanide and actinide metallocenes†
TLDR
An intuitive model is presented to show how similar covalent contributions to the ground state can have different impacts on the overall stability of f-element metallocenes and is comparable in magnitude to values reported previously for U(C8H8)2.

TLDR

Understanding the Stabilization and Tunability of Divalent Europium 2.2.2B Cryptates.
TLDR
Computational results show that the substitution of a Cl- anion in the place of a methanol molecule causes mixing of the 5d excited states in the Eu(II) 2.2.2B cryptate complex, and magnetism studies reveal the identity of the capping ligand.
Uncovering Heavy Actinide Covalency: Implications for Minor Actinide Partitioning.
TLDR
An overall increase in bonding and also the orbital contribution along the Am-Cf series is clearly due to the enhancement in covalency, which is complementary to the orbital degeneracy induced covalencies proposed very recently by Batista and co-workers.
Homoleptic Imidophosphorane Stabilization of Tetravalent Cerium.
TLDR
Spectroscopic studies reveal the dominant covalent metal-ligand interactions underlying the observed redox chemistry and the dependence of the redox potential on the binding of potassium in the inner coordination sphere.

Theoretical investigation on multiple bonds in terminal actinide nitride complexes.
TLDR
It was found that with increasing actinides atomic number, the bond length of terminal multiple An-N1 bond decreases, in accordance with the actinide contraction, which indicates a decrease in bond strength.

TLDR
Detailed QTAIM analysis of Eu, Gd, Am, and Cm complexes revealed increased covalent character in M-O and M-N bonds when M = An, with this increase being more pronounced in the BTP complexes.

TLDR
Atoms-in-molecules analysis of the electron densities of the title compounds indicates that the An-Cp bonding is very ionic, increasingly so as the actinide becomes heavier.

TLDR
The clarified electronic structures of the investigated AnO3 molecules confirmed the pentavalent character of Am and Cm in their trioxides in contrast to the hexavalent characters of U, Np, and Pu.
Does covalency increase or decrease across the actinide series? Implications for minor actinide partitioning.
TLDR
It is suggested that care must be taken when using quantum chemistry to assess metal-ligand covalency in this part of the periodic table and also topological analysis of the electron density via the quantum theory of atoms-in-molecules.
