The material described by Nd2(RhAl3)3 crystallizes in the orthorhombic Cmcm space group. Nd(1) is bonded in a 17-coordinate geometry to two equivalent Rh(2), four equivalent Rh(1), one Al(1), two equivalent Al(3), two equivalent Al(4), and six equivalent Al(2) atoms. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 8-coordinate geometry to four equivalent Nd(1), two equivalent Al(3), two equivalent Al(4), and four equivalent Al(2) atoms. In the second Rh site, Rh(2) is bonded in a 8-coordinate geometry to four equivalent Nd(1), two equivalent Al(1), two equivalent Al(3), and four equivalent Al(2) atoms. There are four inequivalent Al sites. In the first Al site, Al(1) is bonded in a 2-coordinate geometry to two equivalent Nd(1) and two equivalent Rh(2) atoms. In the second Al site, Al(2) is bonded in a 3-coordinate geometry to three equivalent Nd(1), one Rh(2), and two equivalent Rh(1) atoms. In the third Al site, Al(3) is bonded in a 3-coordinate geometry to two equivalent Nd(1), one Rh(2), and two equivalent Rh(1) atoms. In the fourth Al site, Al(4) is bonded in a 2-coordinate geometry to two equivalent Nd(1) and two equivalent Rh(1) atoms. is represented by the CIF file [CIF]
