The strength of actinide-element bonds from the quantum theory of atoms-in-molecules

Dalton Transactions - 16 October, 2014 - 18:54

Dalton Trans., 2014, Advance Article
DOI: 10.1039/C4DT02323D, PaperQian-Rui Huang, Jennifer R. Kingham, Nikolas Kaltsoyannis
Excellent correlation is found between standard QTAIM metrics and An-N bond lengths, and with N-N bond lengths and vibrational frequencies, but much poorer correlations exist with An-N and An-O interaction energies. Superior correlations are found between interaction energies and the change in the QTAIM charge on compound formation.
