KCaCl3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. K(1) is bonded to twelve equivalent Cl(1) atoms to form distorted KCl12 cuboctahedra that share corners with twelve equivalent K(1)Cl12 cuboctahedra, faces with six equivalent K(1)Cl12 cuboctahedra, and faces with eight equivalent Ca(1)Cl6 octahedra. Ca(1) is bonded to six equivalent Cl(1) atoms to form CaCl6 octahedra that share corners with six equivalent Ca(1)Cl6 octahedra and faces with eight equivalent K(1)Cl12 cuboctahedra. The corner-sharing octahedra are not tilted. Cl(1) is bonded in a linear geometry to four equivalent K(1) and two equivalent Ca(1) atoms.
