Materials Data on Ac3Ce by Materials Project

Abstract

Ac3Ce is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Ac is bonded to eight equivalent Ac and four equivalent Ce atoms to form AcAc8Ce4 cuboctahedra that share corners with twelve equivalent AcAc8Ce4 cuboctahedra, edges with eight equivalent CeAc12 cuboctahedra, edges with sixteen equivalent AcAc8Ce4 cuboctahedra, faces with four equivalent CeAc12 cuboctahedra, and faces with fourteen equivalent AcAc8Ce4 cuboctahedra. All Ac–Ac bond lengths are 3.83 Å. All Ac–Ce bond lengths are 3.83 Å. Ce is bonded to twelve equivalent Ac atoms to form CeAc12 cuboctahedra that share corners with twelve equivalent CeAc12 cuboctahedra, edges with twenty-four equivalent AcAc8Ce4 cuboctahedra, faces with six equivalent CeAc12 cuboctahedra, and faces with twelve equivalent AcAc8Ce4 cuboctahedra.
