Abstract The 750° and 550 °C isotherms of the Cu2FeSnS4-Cu2ZnSnS4 pseudobinary system are investigated by the evacuated silica tube technique using molten halides fluxes. The continuous variation of the a and c parameters as a function of composition points to a complete solid solution between the two end-members, in spite of the different space groups (Cu2FeSnS4: I4̅2m ; Cu2ZnSnS4: I4̅). Although the possible mechanism of substitution between Fe and Zn and/or between (Fe,Zn) and Cu remains unclear, the space group transition is found to occur in the compositional range 60-70 mole % Cu2ZnSnS4.
