On the basis of crystallographic structures of over 1000 lanthanide complexes, the electronegativity of lanthanides and lanthanide-oygen bond length are quantitatively calculated by the bond valence model. Some relationships among the electronegativity, bond length, lanthanide atomic number and lanthanide coordination number in various lanthanide metal-organic complexes are found in this work. The electronegativity decreases with an increase in the lanthanide coordination number and increases with an increase in the lanthamide atomic number. The lanthanide-oxygen bond length decreases with an increase in the lanthanide atomic number and increases with an increase in the lanthanide coordination number. (C) 2004 Elsevier B.V.
