Abstract. In order to obtain the accurate crystal field parameters in different models of crystal field theory is necessary to optimize the geometry of the host matrices before and after doping. The present work is devoted to optimization the geometry of SrIn2O4 spinel doped with Eu3+ in the frame of the shell model and pair approximation. By doping the Eu3+ will substitute the In3+ ion, in octahedral site symmetry and this new structure has been optimized.
