BaH2O3 crystallizes in the orthorhombic Pmc2_1 space group. Ba(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), and four equivalent O(3) atoms. H(1) is bonded in a distorted linear geometry to one O(1) and one O(2) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a water-like geometry to two equivalent Ba(1) and two equivalent H(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Ba(1) and two equivalent H(1) atoms. In the third O site, O(3) is bonded in a square co-planar geometry to four equivalent Ba(1) atoms.
BaH2O3 crystallizes in the orthorhombic Pmc2_1 space group. Ba(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), and four equivalent O(3) atoms. There is one shorter (2.80 Å) and one longer (2.83 Å) Ba(1)-O(1) bond length. Both Ba(1)-O(2) bond lengths are 2.76 Å. There are two shorter (2.83 Å) and two longer (2.86 Å) Ba(1)-O(3) bond lengths. H(1) is bonded in a distorted linear geometry to one O(1) and one O(2) atom. The H(1)-O(1) bond length is 1.03 Å. The H(1)-O(2) bond length is 1.59 Å. There are three inequivalent O sites. In the first O site, O(1) is bonded in a water-like geometry to two equivalent Ba(1) and two equivalent H(1) atoms.
