Tm3AlN is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. Tm(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 Tm(1) atoms to form AlTm12 cuboctahedra that share corners with twelve equivalent Al(1)Tm12 cuboctahedra, faces with six equivalent Al(1)Tm12 cuboctahedra, and faces with eight equivalent N(1)Tm6 octahedra. N(1) is bonded to six equivalent Tm(1) atoms to form NTm6 octahedra that share corners with six equivalent N(1)Tm6 octahedra and faces with eight equivalent Al(1)Tm12 cuboctahedra. The corner-sharing octahedra are not tilted.
Tm3AlN is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. Tm(1) is bonded in a linear geometry to four equivalent Al(1) and two equivalent N(1) atoms. All Tm(1)-Al(1) bond lengths are 3.29 Å. Both Tm(1)-N(1) bond lengths are 2.33 Å. Al(1) is bonded to twelve equivalent Tm(1) atoms to form AlTm12 cuboctahedra that share corners with twelve equivalent Al(1)Tm12 cuboctahedra, faces with six equivalent Al(1)Tm12 cuboctahedra, and faces with eight equivalent N(1)Tm6 octahedra. N(1) is bonded to six equivalent Tm(1) atoms to form NTm6 octahedra that share corners with six equivalent N(1)Tm6 octahedra and faces with eight equivalent Al(1)Tm12 cuboctahedra.
