Title: Materials Data on AcCe3 by Materials Project

Abstract

AcCe3 is alpha La-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Ac is bonded to twelve Ce atoms to form AcCe12 cuboctahedra that share corners with four equivalent AcCe12 cuboctahedra, corners with eight equivalent CeAc4Ce8 cuboctahedra, edges with eight equivalent AcCe12 cuboctahedra, edges with sixteen equivalent CeAc4Ce8 cuboctahedra, faces with four equivalent AcCe12 cuboctahedra, and faces with fourteen CeAc4Ce8 cuboctahedra. There are four shorter (3.53 Å) and eight longer (3.54 Å) Ac–Ce bond lengths. There are two inequivalent Ce sites. In the first Ce site, Ce is bonded to four equivalent Ac and eight Ce atoms to form CeAc4Ce8 cuboctahedra that share corners with twelve equivalent CeAc4Ce8 cuboctahedra, edges with eight equivalent AcCe12 cuboctahedra, edges with sixteen CeAc4Ce8 cuboctahedra, faces with four equivalent AcCe12 cuboctahedra, and faces with fourteen CeAc4Ce8 cuboctahedra. There are four shorter (3.53 Å) and four longer (3.54 Å) Ce–Ce bond lengths. In the second Ce site, Ce is bonded to four equivalent Ac and eight equivalent Ce atoms to form CeAc4Ce8 cuboctahedra that share corners with four equivalent CeAc4Ce8 cuboctahedra, corners with eight equivalent AcCe12 cuboctahedra, edges with twenty-four CeAc4Ce8 cuboctahedra, faces with six equivalent AcCe12 cuboctahedra, and faces withmore » twelve CeAc4Ce8 cuboctahedra.« less
