Analysis of lanthanide pi-complexes containing N,P, and As atoms

摘要

A sampling comprising 92 LnC_nH_mQ_k pi-complexes (Ln = Sc, Y,or lanthanides; Q = N, P, As) was used to analyze the influence of the nature, the oxidation state, and the coordination number of the central Ln atom and the nature of the Q atom on the parameters of the lanthanide action area. The effect of steric factors on the stability of complex groups and on the presence (or absence) of agostic interactions in the structures of these complexes was studied. A number of crystal structure features found previously for lanthanide pi-complexes of a different stoichiometric composition was confirmed for the structures of the given complexes.
