A tetragonal rutile-type ceramic substitutional solid solution of the composition Cr<sub>1−m>x m>sub>Fe<sub>m>x m>sub>SnSbO<sub>6sub>, was found to form in the CrSnSbO<sub>6sub>–FeSnSbO<sub>6sub> system in the range 0.0<m>x m><1.0. The new phase was obtained by the high-temperature solid-state reaction. The monophase samples containing Cr<sub>1−m>x m>sub>Fe<sub>m>x m>sub>SnSbO<sub>6sub> were characterised by powder XRD, DTA–TGA, IR, UV–vis-DRS and SEM/EDX methods. The influence of the degree of Fe<sup>3+sup> ion incorporation in the crystal lattice of CrSnSbO<sub>6sub> replacing Cr<sup>3+sup> ions, on the thermal stability, unit cell volume, band gap energies, chromaticity coordinates m>L m>*, m>a m>* and m>b m>* as well as on the position of the IR absorption bands in the spectrum of Cr<sub>1−m>x m>sub>Fe<sub>m>x m>sub>SnSbO<sub>6sub> was determined. The morphology of FeSnSbO<sub>6sub>, CrSnSbO<sub>6sub>, and solid solution was analysed. Some properties of the new solid solution Cr<sub>1−m>x m>sub>Fe<sub>m>x m>sub>SnSbO<sub>6sub> were compared with those of the known phase Cr<sub>1−m>x m>sub>Fe<sub>m>x m>sub>VSbO<sub>6sub>.
