Ca(ClO3)2 crystallizes in the orthorhombic Fdd2 space group. Ca(1) is bonded in a 8-coordinate geometry to two equivalent O(2), two equivalent O(3), and four equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to two equivalent Ca(1) and one Cl(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Ca(1) and one Cl(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Ca(1) and one Cl(1) atom. Cl(1) is bonded in a trigonal non-coplanar geometry to one O(1), one O(2), and one O(3) atom.
Ca(ClO3)2 crystallizes in the orthorhombic Fdd2 space group. Ca(1) is bonded in a 8-coordinate geometry to two equivalent O(2), two equivalent O(3), and four equivalent O(1) atoms. Both Ca(1)-O(2) bond lengths are 2.41 Å. Both Ca(1)-O(3) bond lengths are 2.43 Å. There are two shorter (2.56 Å) and two longer (2.57 Å) Ca(1)-O(1) bond lengths. There are three inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to two equivalent Ca(1) and one Cl(1) atom. The O(1)-Cl(1) bond length is 1.51 Å. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Ca(1) and one Cl(1) atom. The O(2)-Cl(1) bond length is 1.47 Å. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Ca(1) and one Cl(1) atom. The O(3)-Cl(1) bond length is 1.48 Å. Cl(1) is bonded in a trigonal non-coplanar geometry to one O(1), one O(2), and one O(3) atom.
