Materials Data on K3Na by Materials Project

Abstract

K3Na 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 Na atoms to form distorted KK8Na4 cuboctahedra that share corners with twelve equivalent KK8Na4 cuboctahedra, edges with eight equivalent NaK12 cuboctahedra, edges with sixteen equivalent KK8Na4 cuboctahedra, faces with four equivalent NaK12 cuboctahedra, and faces with fourteen equivalent KK8Na4 cuboctahedra. All K–K bond lengths are 4.46 Å. All K–Na bond lengths are 4.46 Å. Na is bonded to twelve equivalent K atoms to form distorted NaK12 cuboctahedra that share corners with twelve equivalent NaK12 cuboctahedra, edges with twenty-four equivalent KK8Na4 cuboctahedra, faces with six equivalent NaK12 cuboctahedra, and faces with twelve equivalent KK8Na4 cuboctahedra.
