KPm3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. K(1) is bonded to twelve equivalent Pm(1) atoms to form KPm12 cuboctahedra that share corners with twelve equivalent K(1)Pm12 cuboctahedra, edges with twenty-four equivalent Pm(1)K4Pm8 cuboctahedra, faces with six equivalent K(1)Pm12 cuboctahedra, and faces with twelve equivalent Pm(1)K4Pm8 cuboctahedra. Pm(1) is bonded to four equivalent K(1) and eight equivalent Pm(1) atoms to form PmK4Pm8 cuboctahedra that share corners with twelve equivalent Pm(1)K4Pm8 cuboctahedra, edges with eight equivalent K(1)Pm12 cuboctahedra, edges with sixteen equivalent Pm(1)K4Pm8 cuboctahedra, faces with four equivalent K(1)Pm12 cuboctahedra, and faces with fourteen equivalent Pm(1)K4Pm8 cuboctahedra.
