Materials Data on Zn3CrSe4 by Materials Project
CrZn3Se4 is Lavarevi\'{c}ite structured and crystallizes in the cubic P-43m space group. The structure is three-dimensional. Cr2+ is bonded to four equivalent Se2- atoms to form CrSe4 tetrahedra that share corners with twelve equivalent ZnSe4 tetrahedra. All Cr–Se bond lengths are 2.50 Å. Zn2+ is bonded to four equivalent Se2- atoms to form ZnSe4 tetrahedra that share corners with four equivalent CrSe4 tetrahedra and corners with eight equivalent ZnSe4 tetrahedra. All Zn–Se bond lengths are 2.49 Å. Se2- is bonded to one Cr2+ and three equivalent Zn2+ atoms to form corner-sharing SeZn3Cr tetrahedra.
