The structure described by Zn3Se is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Zn(1) is bonded in a distorted see-saw-like geometry to four equivalent Se(1) atoms. Se(1) is bonded to twelve equivalent Zn(1) atoms to form a mixture of face and corner-sharing SeZn12 cuboctahedra. is represented by the CIF file [CIF]
