We present combined X-ray powder diffraction and Mössbauer ^{119}Sn studies of polycrystalline compounds with a general formula Zn_xSn_yCr_zSe_4 (where x+y+z ≈3). The obtained single-phase compounds crystallize in the spinel cubic structure - Fd3m. Tin ions are found to occupy both tetrahedral and octahedral sublattices. On the contrary to the strong tetrahedral site preference energy of Sn, the presented data strongly suggest that the increase in lattice parameters with Sn doping is caused by Sn ions that incorporated into octahedral positions. A quadrupole and isomer shifts of ^{119}Sn in (SnSe_4)^{6-} and (SnSe_6)^{4-} are also reported.
