The structure described by Pm3Zn crystallizes in the hexagonal P6_3/mmc space group. Pm(1) is bonded in a 12-coordinate geometry to eight equivalent Pm(1) and four equivalent Zn(1) atoms. Zn(1) is bonded to twelve equivalent Pm(1) atoms to form a mixture of face and corner-sharing ZnPm12 cuboctahedra. is represented by the CIF file [CIF]
