Rb2NdBr5 crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 8-coordinate geometry to two equivalent Br(1), two equivalent Br(2), two equivalent Br(3), and two equivalent Br(4) atoms. Nd(1) is bonded to one Br(1), one Br(3), one Br(4), and four equivalent Br(2) atoms to form distorted edge-sharing NdBr7 pentagonal bipyramids. There are four inequivalent Br sites. In the first Br site, Br(1) is bonded to four equivalent Rb(1) and one Nd(1) atom to form a mixture of distorted edge and corner-sharing BrRb4Nd trigonal bipyramids. In the second Br site, Br(2) is bonded in a 4-coordinate geometry to two equivalent Rb(1) and two equivalent Nd(1) atoms. In the third Br site, Br(3) is bonded to four equivalent Rb(1) and one Nd(1) atom to form a mixture of distorted edge, face, and corner-sharing BrRb4Nd trigonal bipyramids. In the fourth Br site, Br(4) is bonded to four equivalent Rb(1) and one Nd(1) atom to form a mixture of distorted edge, face, and corner-sharing BrRb4Nd trigonal bipyramids.
