Rb2NdCl5 crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 8-coordinate geometry to two equivalent Cl(1), two equivalent Cl(2), two equivalent Cl(3), and two equivalent Cl(4) atoms. Nd(1) is bonded to one Cl(1), one Cl(2), one Cl(3), and four equivalent Cl(4) atoms to form distorted edge-sharing NdCl7 pentagonal bipyramids. There are four inequivalent Cl sites. In the first Cl site, Cl(1) is bonded to four equivalent Rb(1) and one Nd(1) atom to form a mixture of distorted corner, edge, and face-sharing ClRb4Nd trigonal bipyramids. In the second Cl site, Cl(2) is bonded in a 5-coordinate geometry to four equivalent Rb(1) and one Nd(1) atom. In the third Cl site, Cl(3) is bonded to four equivalent Rb(1) and one Nd(1) atom to form a mixture of distorted corner, edge, and face-sharing ClRb4Nd trigonal bipyramids. In the fourth Cl site, Cl(4) is bonded in a 4-coordinate geometry to two equivalent Rb(1) and two equivalent Nd(1) atoms.
