Ca(O2Cl)2 crystallizes in the triclinic P-1 space group. Ca(1) is bonded in a 8-coordinate geometry to one O(2), one O(3), one O(4), two equivalent O(1), and three equivalent Cl(2) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Ca(1) and one O(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Ca(1) and one O(4) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Ca(1) and one Cl(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one Ca(1) and one O(2) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a single-bond geometry to one O(3) atom. In the second Cl site, Cl(2) is bonded in a trigonal non-coplanar geometry to three equivalent Ca(1) atoms.
