(YH12(O3Cl)2)2Cl2 crystallizes in the monoclinic P2/c space group. The structure consists of two hydrochloric acid atoms inside a YH12(O3Cl)2 framework. In the YH12(O3Cl)2 framework, Y(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent Cl(2) atoms. There are six inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(1) and one Cl(2) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(1) atom. In the third H site, H(3) is bonded in a single-bond geometry to one O(2) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one O(2) and one Cl(2) atom. In the fifth H site, H(5) is bonded in a single-bond geometry to one O(3) and one Cl(2) atom. In the sixth H site, H(6) is bonded in a single-bond geometry to one O(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted water-like geometry to one Y(1), one H(1), and one H(2) atom. In the second O site, O(2) is bonded in a water-like geometry to one Y(1), one H(3), and one H(4) atom. In the third O site, O(3) is bonded in a water-like geometry to one Y(1), one H(5), and one H(6) atom. Cl(2) is bonded in a 4-coordinate geometry to one Y(1), one H(1), one H(4), and one H(5) atom.
