BaYCl5 crystallizes in the monoclinic C2/c space group. Ba(1) is bonded in a 10-coordinate geometry to two equivalent Cl(1), two equivalent Cl(3), and six equivalent Cl(2) atoms. Y(1) is bonded in a 8-coordinate geometry to two equivalent Cl(2), two equivalent Cl(3), and four equivalent Cl(1) atoms. There are three inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted trigonal non-coplanar geometry to one Ba(1) and two equivalent Y(1) atoms. In the second Cl site, Cl(2) is bonded to three equivalent Ba(1) and one Y(1) atom to form a mixture of corner and edge-sharing ClBa3Y tetrahedra. In the third Cl site, Cl(3) is bonded in a 4-coordinate geometry to two equivalent Ba(1) and two equivalent Y(1) atoms.
BaYCl5 crystallizes in the monoclinic C2/c space group. Ba(1) is bonded in a 10-coordinate geometry to two equivalent Cl(1), two equivalent Cl(3), and six equivalent Cl(2) atoms. Both Ba(1)-Cl(1) bond lengths are 3.23 Å. Both Ba(1)-Cl(3) bond lengths are 3.55 Å. There are a spread of Ba(1)-Cl(2) bond distances ranging from 3.23-3.34 Å. Y(1) is bonded in a 8-coordinate geometry to two equivalent Cl(2), two equivalent Cl(3), and four equivalent Cl(1) atoms. Both Y(1)-Cl(2) bond lengths are 2.75 Å.
