The structure described by KCa3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. K(1) is bonded to twelve equivalent Ca(1) atoms to form KCa12 cuboctahedra that share corners with twelve equivalent K(1)Ca12 cuboctahedra, edges with twenty-four equivalent Ca(1)K4Ca8 cuboctahedra, faces with six equivalent K(1)Ca12 cuboctahedra, and faces with twelve equivalent Ca(1)K4Ca8 cuboctahedra. Ca(1) is bonded to four equivalent K(1) and eight equivalent Ca(1) atoms to form CaK4Ca8 cuboctahedra that share corners with twelve equivalent Ca(1)K4Ca8 cuboctahedra, edges with eight equivalent K(1)Ca12 cuboctahedra, edges with sixteen equivalent Ca(1)K4Ca8 cuboctahedra, faces with four equivalent K(1)Ca12 cuboctahedra, and faces with fourteen equivalent Ca(1)K4Ca8 cuboctahedra. is represented by the CIF file [CIF]
