CaCl2 is Hydrophilite structured and crystallizes in the orthorhombic Pnnm space group. Ca(1) is bonded to six equivalent Cl(1) atoms to form a mixture of corner and edge-sharing CaCl6 octahedra. The corner-sharing octahedral tilt angles are 50°. Cl(1) is bonded in a trigonal planar geometry to three equivalent Ca(1) atoms.
