Abstract
Molecular structure of EuBr2 was studied by electron diffraction and mass s pectrometry at 1373(20) K. The molecule has a nonlinear equilibrium configu ration and is characterized by the following effective parameter: r(g)(Eu-B r) = 2.767(6) Angstrom, r(g)(Br-Br) = 5.11(5) Angstrom, l(g)(Eu-Br) = 0.109 (2) Angstrom, l(g)(Br-Br) = 0.388(5) Angstrom, angle (g)(Br-Eu-Br) = 135.0( 3.5)degrees. The vibration frequencies v(1) = 225(10) cm(-1) and v(2) = 40( 4) cm(-1) were found using electron diffraction data.
