Materials Data on K3Lu by Materials Project

Abstract

K3Lu is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. K is bonded to eight equivalent K and four equivalent Lu atoms to form distorted KK8Lu4 cuboctahedra that share corners with twelve equivalent KK8Lu4 cuboctahedra, edges with eight equivalent LuK12 cuboctahedra, edges with sixteen equivalent KK8Lu4 cuboctahedra, faces with four equivalent LuK12 cuboctahedra, and faces with fourteen equivalent KK8Lu4 cuboctahedra. All K–K bond lengths are 4.30 Å. All K–Lu bond lengths are 4.30 Å. Lu is bonded to twelve equivalent K atoms to form LuK12 cuboctahedra that share corners with twelve equivalent LuK12 cuboctahedra, edges with twenty-four equivalent KK8Lu4 cuboctahedra, faces with six equivalent LuK12 cuboctahedra, and faces with twelve equivalent KK8Lu4 cuboctahedra.
