PmSe is Wurtzite structured and crystallizes in the hexagonal P6_3mc space group. Pm(1) is bonded to four equivalent Se(1) atoms to form corner-sharing PmSe4 tetrahedra. Se(1) is bonded to four equivalent Pm(1) atoms to form corner-sharing SePm4 tetrahedra.
PmSe is Wurtzite structured and crystallizes in the hexagonal P6_3mc space group. Pm(1) is bonded to four equivalent Se(1) atoms to form corner-sharing PmSe4 tetrahedra. There is one shorter (2.83 Å) and three longer (2.86 Å) Pm(1)-Se(1) bond lengths. Se(1) is bonded to four equivalent Pm(1) atoms to form corner-sharing SePm4 tetrahedra.
