LiAc3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Li(1) is bonded to twelve equivalent Ac(1) atoms to form LiAc12 cuboctahedra that share corners with twelve equivalent Li(1)Ac12 cuboctahedra, edges with twenty-four equivalent Ac(1)Li4Ac8 cuboctahedra, faces with six equivalent Li(1)Ac12 cuboctahedra, and faces with twelve equivalent Ac(1)Li4Ac8 cuboctahedra. Ac(1) is bonded to four equivalent Li(1) and eight equivalent Ac(1) atoms to form AcLi4Ac8 cuboctahedra that share corners with twelve equivalent Ac(1)Li4Ac8 cuboctahedra, edges with eight equivalent Li(1)Ac12 cuboctahedra, edges with sixteen equivalent Ac(1)Li4Ac8 cuboctahedra, faces with four equivalent Li(1)Ac12 cuboctahedra, and faces with fourteen equivalent Ac(1)Li4Ac8 cuboctahedra.
