CaZnSe2 is Enargite-like structured and crystallizes in the tetragonal P-4m2 space group. Ca(1) is bonded to four equivalent Se(1) atoms to form CaSe4 tetrahedra that share corners with four equivalent Ca(1)Se4 tetrahedra and corners with eight 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 Zn(1)Se4 tetrahedra and corners with eight equivalent Ca(1)Se4 tetrahedra. Se(1) is bonded to two equivalent Ca(1) and two equivalent Zn(1) atoms to form corner-sharing SeCa2Zn2 tetrahedra.
