Europium complexes in the + 3 oxidation state, with coordination numbers si
x, seven, eight, nine and ten are under consideration. In most cases, singl
e crystals or isomorphous compounds were studied by X-ray structural analys
es. An attempt is made to correlate the results with the emission spectrum
interpretation. Only articles containing both aspects are included in this
review. Some general remarks concerning different coordination numbered com
plexes are also presented. (C) 2000 Elsevier Science S.A. All rights reserv
