Europium Tricyclopentadienide

Zeitschrift für Naturforschung B, 1966
Europium tricyclopentadienide has been prepared by the reaction of dichloroeuropium cyclopentadienide with two equivalents of sodium dicyclopentadienide as well as by the reaction of europium trichloride with three equivalents of sodium cyclopentadienide, both reactions taking place in tetrahydrofuran. It is stable in vacuum at temperatures up to 70°C.

Europium-151 Mössbauer Effect Study of Relaxation in Two Bi(pentamethylcyclopentadienyl) Europium(II) Complexes

, 1988
Europium-151 Mössbauer spectra of two bis(pentamethylcyclopentadienyl) europium complexes have been recorded at 78K. The broad spectra with linewidths of 14.2 and 11.6 mm/s, and with isomer shifts of -12.5 and -12.8 mm/s, relative to EuF3 may be ...
