Materials Data on KCe3 by Materials Project

Abstract

KCe3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. K is bonded to twelve equivalent Ce atoms to form KCe12 cuboctahedra that share corners with twelve equivalent KCe12 cuboctahedra, edges with twenty-four equivalent CeK4Ce8 cuboctahedra, faces with six equivalent KCe12 cuboctahedra, and faces with twelve equivalent CeK4Ce8 cuboctahedra. All K–Ce bond lengths are 3.61 Å. Ce is bonded to four equivalent K and eight equivalent Ce atoms to form CeK4Ce8 cuboctahedra that share corners with twelve equivalent CeK4Ce8 cuboctahedra, edges with eight equivalent KCe12 cuboctahedra, edges with sixteen equivalent CeK4Ce8 cuboctahedra, faces with four equivalent KCe12 cuboctahedra, and faces with fourteen equivalent CeK4Ce8 cuboctahedra. All Ce–Ce bond lengths are 3.61 Å.
