The material structure described by AcPr3 is Magnesium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. Ac(1) is bonded to twelve equivalent Pr(1) atoms to form AcPr12 cuboctahedra that share corners with six equivalent Ac(1)Pr12 cuboctahedra, corners with twelve equivalent Pr(1)Ac4Pr8 cuboctahedra, edges with eighteen equivalent Pr(1)Ac4Pr8 cuboctahedra, faces with eight equivalent Ac(1)Pr12 cuboctahedra, and faces with twelve equivalent Pr(1)Ac4Pr8 cuboctahedra. Pr(1) is bonded to four equivalent Ac(1) and eight equivalent Pr(1) atoms to form PrAc4Pr8 cuboctahedra that share corners with four equivalent Ac(1)Pr12 cuboctahedra, corners with fourteen equivalent Pr(1)Ac4Pr8 cuboctahedra, edges with six equivalent Ac(1)Pr12 cuboctahedra, edges with twelve equivalent Pr(1)Ac4Pr8 cuboctahedra, faces with four equivalent Ac(1)Pr12 cuboctahedra, and faces with sixteen equivalent Pr(1)Ac4Pr8 cuboctahedra. is represented by the CIF file [CIF]
