Abstract

Symmetry and electrostatic equilibrium in europium compounds are revisited with the aim of improving the role of obtaining the charge factors (g_j), of the nearest neighbours (NN) of the lanthanide site, j running over the NN, now using the g_j vs. R_j (the NN position) linear behaviour. An inferior limit of the g_j position is predicted. Further, an indication that the $B^{\rm 4}_{q}$ and $B^{\rm 6}_{q}$ crystal field parameters may not exactly depend on g_j or R_j in the same way as the $B^{\rm 2}_{q}$ parameter is, at least, made.
