The crystals of the title compound are composed of a polymeric network comp
osed of europium(II) cations, hydrogen sulfosalicylate (2-hydroxy-5-sulfona
tobenzoate) anions and coordinated water molecules. The first coordination
sphere of the metal cation is composed of two carboxylic oxygen atoms, two
sulfonate ones and five water molecules. The simultaneous coordination of s
ulfosalicylate moiety through carboxylate and sulfonate groups results in a
very long b axis. (C) 2000 Elsevier Science S.A. All rights reserved.
