Abstract

The title compounds crystallize in the cubic space group Fd3m, Z = 8, with cell parameters of 8.2958(37) Å for NiFeGaO4 and 8.3921(24) Å for ZnFeGaO4. By comparison of experimental and calculated patterns with various site distribution models, ZnFeGaO4 has been determined to have the normal spinel structure and NiFeGaO4 a dominantly inverse spinel structure.
