The crystal structure of the title compound was determined at 293 and 100 K
. The structure contains bis(triethanolamine)europium(II) cations, and perc
hlorate anions. The metal ion coordination environment is composed of two N
and six O atoms. At room temperature, all triethanolamine molecules are pa
rtially disordered. On going to 100 K, the disorder partially disappears, g
iving rise to a commensurate modulation of the structure. (C) 2001 Elsevier
