PaOsO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. Pa(1) is bonded to twelve equivalent O(1) atoms to form PaO12 cuboctahedra that share corners with twelve equivalent Pa(1)O12 cuboctahedra, faces with six equivalent Pa(1)O12 cuboctahedra, and faces with eight equivalent Os(1)O6 octahedra. Os(1) is bonded to six equivalent O(1) atoms to form OsO6 octahedra that share corners with six equivalent Os(1)O6 octahedra and faces with eight equivalent Pa(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded to four equivalent Pa(1) and two equivalent Os(1) atoms to form a mixture of distorted corner, edge, and face-sharing OPa4Os2 octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
