The material structure described by Nd2Co3Al9 crystallizes in the orthorhombic Cmcm space group. Nd(1) is bonded in a 11-coordinate geometry to one Al(2), two equivalent Al(3), two equivalent Al(4), and six equivalent Al(1) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 8-coordinate geometry to two equivalent Al(3), two equivalent Al(4), and four equivalent Al(1) atoms. In the second Co site, Co(2) is bonded in a 8-coordinate geometry to two equivalent Al(2), two equivalent Al(3), and four equivalent Al(1) atoms. There are four inequivalent Al sites. In the first Al site, Al(1) is bonded in a 11-coordinate geometry to three equivalent Nd(1), one Co(2), two equivalent Co(1), one Al(2), one Al(3), one Al(4), and two equivalent Al(1) atoms. In the second Al site, Al(2) is bonded in a 10-coordinate geometry to two equivalent Nd(1), two equivalent Co(2), two equivalent Al(4), and four equivalent Al(1) atoms. In the third Al site, Al(3) is bonded in a 3-coordinate geometry to two equivalent Nd(1), one Co(2), two equivalent Co(1), two equivalent Al(1), and two equivalent Al(4) atoms. In the fourth Al site, Al(4) is bonded in a 10-coordinate geometry to two equivalent Nd(1), two equivalent Co(1), one Al(2), one Al(4), two equivalent Al(1), and two equivalent Al(3) atoms. is represented by the CIF file [CIF]
