CaCl2 crystallizes in the orthorhombic Pnma space group. Ca(1) is bonded to two equivalent Cl(1) and three equivalent Cl(2) atoms to form a mixture of distorted corner and edge-sharing CaCl5 trigonal bipyramids. There are two inequivalent Cl sites. In the first Cl site, Cl(2) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Ca(1) atoms. In the second Cl site, Cl(1) is bonded in a bent 150 degrees geometry to two equivalent Ca(1) atoms.
CaCl2 crystallizes in the orthorhombic Pnma space group. Ca(1) is bonded to two equivalent Cl(1) and three equivalent Cl(2) atoms to form a mixture of distorted corner and edge-sharing CaCl5 trigonal bipyramids. There is one shorter (2.61 Å) and one longer (2.65 Å) Ca(1)-Cl(1) bond length. There are two shorter (2.74 Å) and one longer (2.80 Å) Ca(1)-Cl(2) bond length. There are two inequivalent Cl sites. In the first Cl site, Cl(2) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Ca(1) atoms. In the second Cl site, Cl(1) is bonded in a bent 150 degrees geometry to two equivalent Ca(1) atoms.
