BaC2H2O5 crystallizes in the monoclinic C2/m space group. Ba(1) is bonded in a 10-coordinate geometry to two equivalent O(3), four equivalent O(1), and four equivalent O(2) atoms. C(1) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. H(1) 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 single-bond geometry to two equivalent Ba(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Ba(1) and one C(1) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to two equivalent Ba(1) and two equivalent H(1) atoms.
