BaHBr is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Ba(1) is bonded in a 9-coordinate geometry to four equivalent H(1) and five equivalent Br(1) atoms. H(1) is bonded to four equivalent Ba(1) atoms to form a mixture of corner and edge-sharing HBa4 tetrahedra. Br(1) is bonded in a 5-coordinate geometry to five equivalent Ba(1) atoms.
BaHBr is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Ba(1) is bonded in a 9-coordinate geometry to four equivalent H(1) and five equivalent Br(1) atoms. All Ba(1)-H(1) bond lengths are 2.70 Å. There are four shorter (3.42 Å) and one longer (3.44 Å) Ba(1)-Br(1) bond length. H(1) is bonded to four equivalent Ba(1) atoms to form a mixture of corner and edge-sharing HBa4 tetrahedra. Br(1) is bonded in a 5-coordinate geometry to five equivalent Ba(1) atoms.
