Abstract

Mössbauer spectra of the dimer of a bimetallic Eu‐Al complex, [(CF3COO)3EuHAl(C2H5)2 · 2 THF]2 are measured at different temperatures (81 to 166 K) and some Mössbauer parameters, such as isomer shift, electric quadrupole splitting and asymmetric parameter, are derived from the experimental spectra. The Debye temperature of the compound determined by a Debye model is 128 K. The results indicate that europium in the organo‐europium compound is trivalent and that a bridging hydrogen atom between two europium atoms exists in the dimer. The low Debye temperature implies that the weaker binding force between the europium atom and the lattice may be related to the structure and the chemical bonding in the organometallic compound of europium.
