CsHo2Cl7 crystallizes in the orthorhombic Pnma space group. Cs(1) is bonded in a 10-coordinate geometry to two equivalent Cl(1), two equivalent Cl(2), two equivalent Cl(4), and four equivalent Cl(3) atoms. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded to one Cl(4), two equivalent Cl(1), two equivalent Cl(2), and two equivalent Cl(3) atoms to form a mixture of distorted edge and face-sharing HoCl7 pentagonal bipyramids. In the second Ho site, Ho(2) is bonded to one Cl(4), two equivalent Cl(1), two equivalent Cl(2), and two equivalent Cl(3) atoms to form a mixture of distorted edge and face-sharing HoCl7 pentagonal bipyramids. There are four inequivalent Cl sites. In the first Cl site, Cl(4) is bonded to two equivalent Cs(1), one Ho(1), and one Ho(2) atom to form a mixture of distorted corner and edge-sharing ClCs2Ho2 trigonal pyramids. In the second Cl site, Cl(1) is bonded in a distorted L-shaped geometry to one Cs(1), one Ho(1), and one Ho(2) atom. In the third Cl site, Cl(2) is bonded in a distorted trigonal non-coplanar geometry to one Cs(1), one Ho(1), and one Ho(2) atom. In the fourth Cl site, Cl(3) is bonded to two equivalent Cs(1), one Ho(1), and one Ho(2) atom to form a mixture of distorted corner and edge-sharing ClCs2Ho2 tetrahedra.
