BaHI is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Ba(1) is bonded in a 4-coordinate geometry to four equivalent H(1) and five equivalent I(1) atoms. H(1) is bonded to four equivalent Ba(1) atoms to form a mixture of edge and corner-sharing HBa4 tetrahedra. I(1) is bonded in a 5-coordinate geometry to five equivalent Ba(1) atoms.
BaHI is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Ba(1) is bonded in a 4-coordinate geometry to four equivalent H(1) and five equivalent I(1) atoms. All Ba(1)-H(1) bond lengths are 2.74 Å. There are four shorter (3.62 Å) and one longer (3.79 Å) Ba(1)-I(1) bond length. H(1) is bonded to four equivalent Ba(1) atoms to form a mixture of edge and corner-sharing HBa4 tetrahedra. I(1) is bonded in a 5-coordinate geometry to five equivalent Ba(1) atoms.
