K3Zr is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. K(1) is bonded to eight equivalent K(1) and four equivalent Zr(1) atoms to form distorted KK8Zr4 cuboctahedra that share corners with twelve equivalent K(1)K8Zr4 cuboctahedra, edges with eight equivalent Zr(1)K12 cuboctahedra, edges with sixteen equivalent K(1)K8Zr4 cuboctahedra, faces with four equivalent Zr(1)K12 cuboctahedra, and faces with fourteen equivalent K(1)K8Zr4 cuboctahedra. Zr(1) is bonded to twelve equivalent K(1) atoms to form ZrK12 cuboctahedra that share corners with twelve equivalent Zr(1)K12 cuboctahedra, edges with twenty-four equivalent K(1)K8Zr4 cuboctahedra, faces with six equivalent Zr(1)K12 cuboctahedra, and faces with twelve equivalent K(1)K8Zr4 cuboctahedra.
