名称:
Aqua(ethylenedisulfonato)europium(II) [Eu(O3SC2H4SO3)(H2O)] – Structure, spectroscopy and magnetic properties
摘要:
Aqua(ethylenedisulfonato)europium(II) was obtained by electrochemical reduction. The compound is polymeric and each metal cation is surrounded by six oxygen atoms from sulfonate groups and by two water molecules. The compound shows faint emission with maximum at 414.5 nm at room temperature and bright luminescence (lambda(max) = 408 nm) at 77 K. Magnetic susceptibility measurements show that interactions between Eu2+ cations are very weak; the shortest Eu-Eu distances are in the range 5.0-5.7 angstrom. (C) 2012 Elsevier Ltd.
