The material described by AcTe3 crystallizes in the tetragonal I4/mmm space group. Ac(1) is bonded to four equivalent Te(2) and eight equivalent Te(1) atoms to form distorted AcTe12 cuboctahedra that share corners with four equivalent Ac(1)Te12 cuboctahedra, corners with sixteen equivalent Te(1)Ac4Te4 hexagonal bipyramids, edges with eight equivalent Ac(1)Te12 cuboctahedra, edges with eight equivalent Te(1)Ac4Te4 hexagonal bipyramids, and faces with four equivalent Ac(1)Te12 cuboctahedra. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded to four equivalent Ac(1) and four equivalent Te(1) atoms to form distorted TeAc4Te4 hexagonal bipyramids that share corners with eight equivalent Ac(1)Te12 cuboctahedra, corners with sixteen equivalent Te(1)Ac4Te4 hexagonal bipyramids, edges with four equivalent Ac(1)Te12 cuboctahedra, edges with six equivalent Te(1)Ac4Te4 hexagonal bipyramids, and faces with four equivalent Te(1)Ac4Te4 hexagonal bipyramids. In the second Te site, Te(2) is bonded in a square co-planar geometry to four equivalent Ac(1) atoms. is represented by the CIF card [CIF]
