Materials Data on K3Cr by Materials Project

Abstract

K3Cr 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 Cr atoms to form distorted KK8Cr4 cuboctahedra that share corners with twelve equivalent KK8Cr4 cuboctahedra, edges with eight equivalent CrK12 cuboctahedra, edges with sixteen equivalent KK8Cr4 cuboctahedra, faces with four equivalent CrK12 cuboctahedra, and faces with fourteen equivalent KK8Cr4 cuboctahedra. All K–K bond lengths are 4.18 Å. All K–Cr bond lengths are 4.18 Å. Cr is bonded to twelve equivalent K atoms to form distorted CrK12 cuboctahedra that share corners with twelve equivalent CrK12 cuboctahedra, edges with twenty-four equivalent KK8Cr4 cuboctahedra, faces with six equivalent CrK12 cuboctahedra, and faces with twelve equivalent KK8Cr4 cuboctahedra.
