The structure described by Ca(IO3)2 crystallizes in the monoclinic P2_1/c space group. Ca(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), one O(3), one O(4), two equivalent O(5), and two equivalent O(6) atoms. There are six inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Ca(1) and one I(2) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Ca(1) and one I(2) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Ca(1) and one I(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Ca(1) and one I(2) atom. In the fifth O site, O(5) is bonded in a 2-coordinate geometry to two equivalent Ca(1) and one I(1) atom. In the sixth O site, O(6) is bonded in a trigonal planar geometry to two equivalent Ca(1) and one I(1) atom. There are two inequivalent I sites. In the first I site, I(1) is bonded in a distorted T-shaped geometry to one O(3), one O(5), and one O(6) atom. In the second I site, I(2) is bonded in a distorted trigonal non-coplanar geometry to one O(1), one O(2), and one O(4) atom. is represented by the Crystallographic Information File (CIF) [CIF]
