The crystal structure described by BaHCl 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 Cl(1) atoms. H(1) is bonded to four equivalent Ba(1) atoms to form HBa4 tetrahedra that share corners with four equivalent H(1)Ba4 tetrahedra, corners with twelve equivalent Cl(1)Ba5 trigonal bipyramids, edges with four equivalent H(1)Ba4 tetrahedra, and edges with four equivalent Cl(1)Ba5 trigonal bipyramids. Cl(1) is bonded to five equivalent Ba(1) atoms to form distorted ClBa5 trigonal bipyramids that share corners with twelve equivalent H(1)Ba4 tetrahedra, corners with four equivalent Cl(1)Ba5 trigonal bipyramids, edges with four equivalent H(1)Ba4 tetrahedra, and edges with eight equivalent Cl(1)Ba5 trigonal bipyramids. is represented by the CIF file [CIF]
