Sm3AlN is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. Sm(1) is bonded in a linear geometry to four equivalent Al(1) and two equivalent N(1) atoms. Al(1) is bonded to twelve equivalent Sm(1) atoms to form AlSm12 cuboctahedra that share corners with twelve equivalent Al(1)Sm12 cuboctahedra, faces with six equivalent Al(1)Sm12 cuboctahedra, and faces with eight equivalent N(1)Sm6 octahedra. N(1) is bonded to six equivalent Sm(1) atoms to form NSm6 octahedra that share corners with six equivalent N(1)Sm6 octahedra and faces with eight equivalent Al(1)Sm12 cuboctahedra. The corner-sharing octahedra are not tilted.
Sm3AlN is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. Sm(1) is bonded in a linear geometry to four equivalent Al(1) and two equivalent N(1) atoms. All Sm(1)-Al(1) bond lengths are 3.47 Å. Both Sm(1)-N(1) bond lengths are 2.45 Å. Al(1) is bonded to twelve equivalent Sm(1) atoms to form AlSm12 cuboctahedra that share corners with twelve equivalent Al(1)Sm12 cuboctahedra, faces with six equivalent Al(1)Sm12 cuboctahedra, and faces with eight equivalent N(1)Sm6 octahedra. N(1) is bonded to six equivalent Sm(1) atoms to form NSm6 octahedra that share corners with six equivalent N(1)Sm6 octahedra and faces with eight equivalent Al(1)Sm12 cuboctahedra.
