Materials Data on K3U by Materials Project

Abstract

K3U 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 U atoms to form distorted KK8U4 cuboctahedra that share corners with twelve equivalent KK8U4 cuboctahedra, edges with eight equivalent UK12 cuboctahedra, edges with sixteen equivalent KK8U4 cuboctahedra, faces with four equivalent UK12 cuboctahedra, and faces with fourteen equivalent KK8U4 cuboctahedra. All K–K bond lengths are 4.33 Å. All K–U bond lengths are 4.33 Å. U is bonded to twelve equivalent K atoms to form UK12 cuboctahedra that share corners with twelve equivalent UK12 cuboctahedra, edges with twenty-four equivalent KK8U4 cuboctahedra, faces with six equivalent UK12 cuboctahedra, and faces with twelve equivalent KK8U4 cuboctahedra.
