Materials Data on PuMgO3 by Materials Project
MgPuO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Mg2+ is bonded to six equivalent O2- atoms to form MgO6 octahedra that share corners with six equivalent MgO6 octahedra and faces with eight equivalent PuO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Mg–O bond lengths are 1.91 Å. Pu4+ is bonded to twelve equivalent O2- atoms to form PuO12 cuboctahedra that share corners with twelve equivalent PuO12 cuboctahedra, faces with six equivalent PuO12 cuboctahedra, and faces with eight equivalent MgO6 octahedra. All Pu–O bond lengths are 2.71 Å. O2- is bonded in a distorted linear geometry to two equivalent Mg2+ and four equivalent Pu4+ atoms.
