The spinels type ZnCr2-2xIn2xS4 are compounds with structure of face centered cubic, these are normal spinels for x=0 and crystallize in the space group Fd3m-Oh7. The system ZnCr2-2xIn2xS4 is of considerable experimental and theoretical interest. The magnetic and crystallographic proper-ties, such as structure and cation distributions have been studied. In this work, we report the be-havior of the lattice constants and the EPR signal of the system ZnCr2-2xIn2xS4 as a function of temperature and Indium molar substitution at concentrations from x = 0.0 to x = 0.50, and tem-peratures between 103 and 293 K.
