Materials Data on K3In by Materials Project

Abstract

K3In 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 In atoms to form distorted KK8In4 cuboctahedra that share corners with twelve equivalent KK8In4 cuboctahedra, edges with eight equivalent InK12 cuboctahedra, edges with sixteen equivalent KK8In4 cuboctahedra, faces with four equivalent InK12 cuboctahedra, and faces with fourteen equivalent KK8In4 cuboctahedra. All K–K bond lengths are 4.12 Å. All K–In bond lengths are 4.12 Å. In is bonded to twelve equivalent K atoms to form InK12 cuboctahedra that share corners with twelve equivalent InK12 cuboctahedra, edges with twenty-four equivalent KK8In4 cuboctahedra, faces with six equivalent InK12 cuboctahedra, and faces with twelve equivalent KK8In4 cuboctahedra.
