Europium(ii) bis[tetrafluoro-2-(pentafluoroethoxy)ethanesulfonate] – structure and spectroscopic properties of a new near-UV emitter

Abstract

A new Eu(II) complex, [Eu(CF3CF2OCF2CF2SO3)2(H2O)] was obtained by electrochemical reduction. It is polymeric and the Eu2+ cation is 8-coordinate (6 oxygen atoms from sulfonate groups and two water molecules, which...
