Materials Data on RbAc3 by Materials Project

Abstract

RbAc3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Rb is bonded to twelve equivalent Ac atoms to form RbAc12 cuboctahedra that share corners with twelve equivalent RbAc12 cuboctahedra, edges with twenty-four equivalent AcRb4Ac8 cuboctahedra, faces with six equivalent RbAc12 cuboctahedra, and faces with twelve equivalent AcRb4Ac8 cuboctahedra. All Rb–Ac bond lengths are 4.11 Å. Ac is bonded to four equivalent Rb and eight equivalent Ac atoms to form AcRb4Ac8 cuboctahedra that share corners with twelve equivalent AcRb4Ac8 cuboctahedra, edges with eight equivalent RbAc12 cuboctahedra, edges with sixteen equivalent AcRb4Ac8 cuboctahedra, faces with four equivalent RbAc12 cuboctahedra, and faces with fourteen equivalent AcRb4Ac8 cuboctahedra. All Ac–Ac bond lengths are 4.11 Å.
