The crystals of the title compound are composed of polymeric bands bui
lt up from triaqua(oxydiacetato-O,O',O'')europium(II) units, and water
of crystallization. The europium cation is surrounded by six oxydiace
tate oxygen atoms and three water molecules. The distances metal-oxyge
n are generally longer than those observed in Eu(III) carboxylates.
