The material described by Pa3O crystallizes in the hexagonal P6_3/mmc space group. Pa(1) is bonded in a distorted see-saw-like geometry to four equivalent O(1) atoms. O(1) is bonded to twelve equivalent Pa(1) atoms to form a mixture of face and corner-sharing OPa12 cuboctahedra. is represented by the CIF file [CIF]
