The structure described by CrZn3Se4 is Lavarevi\'{c}ite structured and crystallizes in the cubic P-43m space group. Cr(1) is bonded to four equivalent Se(1) atoms to form CrSe4 tetrahedra that share corners with twelve equivalent Zn(1)Se4 tetrahedra. Zn(1) is bonded to four equivalent Se(1) atoms to form ZnSe4 tetrahedra that share corners with four equivalent Cr(1)Se4 tetrahedra and corners with eight equivalent Zn(1)Se4 tetrahedra. Se(1) is bonded to one Cr(1) and three equivalent Zn(1) atoms to form corner-sharing SeZn3Cr tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
