Ba(HCl)2 crystallizes in the monoclinic P2_1/c space group. Ba(1) is bonded to one H(1), one H(2), three equivalent Cl(1), and three equivalent Cl(2) atoms to form a mixture of distorted corner and edge-sharing BaH2Cl6 hexagonal bipyramids. There are two inequivalent H sites. In the first H site, H(1) is bonded in a distorted single-bond geometry to one Ba(1) atom. In the second H site, H(2) is bonded in a distorted single-bond geometry to one Ba(1) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted trigonal planar geometry to three equivalent Ba(1) atoms. In the second Cl site, Cl(2) is bonded in a 3-coordinate geometry to three equivalent Ba(1) atoms.

Ba(1) is bonded to one H(1), one H(2), three equivalent Cl(1), and three equivalent Cl(2) atoms to form a mixture of distorted corner and edge-sharing BaH2Cl6 hexagonal bipyramids. The Ba(1)-H(1) bond length is 3.05 Å. The Ba(1)-H(2) bond length is 2.99 Å. There is one shorter (3.10 Å) and two longer (3.13 Å) Ba(1)-Cl(1) bond lengths. There are a spread of Ba(1)-Cl(2) bond distances ranging from 3.12-3.17 Å. There are two inequivalent H sites. In the first H site, H(1) is bonded in a distorted single-bond geometry to one Ba(1) atom. In the second H site, H(2) is bonded in a distorted single-bond geometry to one Ba(1) atom.
