Abstract

On the basis of experimental data the lattice energies for the new compounds Bi_12.5Ln_1.5ReO_24.5 have been calculated using a Born–Haber cycle. It has been discovered that there is a linear dependence between lattice energies and inverse radii of lanthanide ions. It has been established that calculated and experimental lattice energies for Bi_12.5Yb_1.5ReO_24.5 are in a good agreement. For the first time the compound Bi_12.5Yb_1.5ReO_24.5 has been synthesized, its lattice parameters have been determined and its thermochemical characteristics have been measured. The determined unit cell parameters of Bi_12.5Yb_1.5ReO_24.5 suggest that the structure is of cubic type, space group Fm3m, a = 0.55590(6) nm.
