Pr3AlC is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. Pr(1) is bonded in a linear geometry to four equivalent Al(1) and two equivalent C(1) atoms. Al(1) is bonded to twelve equivalent Pr(1) atoms to form AlPr12 cuboctahedra that share corners with twelve equivalent Al(1)Pr12 cuboctahedra, faces with six equivalent Al(1)Pr12 cuboctahedra, and faces with eight equivalent C(1)Pr6 octahedra. C(1) is bonded to six equivalent Pr(1) atoms to form CPr6 octahedra that share corners with six equivalent C(1)Pr6 octahedra and faces with eight equivalent Al(1)Pr12 cuboctahedra. The corner-sharing octahedra are not tilted.
Pr3AlC is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. Pr(1) is bonded in a linear geometry to four equivalent Al(1) and two equivalent C(1) atoms. All Pr(1)-Al(1) bond lengths are 3.63 Å. Both Pr(1)-C(1) bond lengths are 2.57 Å. Al(1) is bonded to twelve equivalent Pr(1) atoms to form AlPr12 cuboctahedra that share corners with twelve equivalent Al(1)Pr12 cuboctahedra, faces with six equivalent Al(1)Pr12 cuboctahedra, and faces with eight equivalent C(1)Pr6 octahedra. C(1) is bonded to six equivalent Pr(1) atoms to form CPr6 octahedra that share corners with six equivalent C(1)Pr6 octahedra and faces with eight equivalent Al(1)Pr12 cuboctahedra. The corner-sharing octahedra are not tilted.
