Abstract
Ninety-six halogen-containing π-complexes of rare-earth elements were studied to reveal how the volume of the area of action of the Ln atom in coordination polyhedra LnC n X m (X = F, Cl, Br) depends on its nature, coordination and oxidation numbers, and on the number of Ln–X bonds. A method was proposed for estimating the ligand sizes in the coordination sphere by making use of the molecular Voronoi–Dirichlet polyhedra. The effect of the ligand sizes on the stability of π-complexes and formation of aghostic contacts in their structures was analyzed.
