The material described by Nd2Rh2CuSi3 crystallizes in the orthorhombic Amm2 space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 14-coordinate geometry to two equivalent Rh(1), two equivalent Rh(2), two equivalent Si(2), four equivalent Si(1), and four equivalent Si(3) atoms. In the second Nd site, Nd(2) is bonded in a 14-coordinate geometry to two equivalent Rh(1), two equivalent Rh(2), four equivalent Cu(1), two equivalent Si(3), and four equivalent Si(2) atoms. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 4-coordinate geometry to two equivalent Nd(1), two equivalent Nd(2), two equivalent Cu(1), and two equivalent Si(1) atoms. In the second Rh site, Rh(2) is bonded in a 4-coordinate geometry to two equivalent Nd(1), two equivalent Nd(2), two equivalent Cu(1), and two equivalent Si(1) atoms. Cu(1) is bonded in a 9-coordinate geometry to four equivalent Nd(2), two equivalent Rh(1), two equivalent Rh(2), and one Si(2) atom. There are three inequivalent Si sites. In the first Si site, Si(1) is bonded in a 4-coordinate geometry to four equivalent Nd(1), two equivalent Rh(1), two equivalent Rh(2), and one Si(3) atom. In the second Si site, Si(2) is bonded in a 9-coordinate geometry to two equivalent Nd(1), four equivalent Nd(2), one Cu(1), and two equivalent Si(3) atoms. In the third Si site, Si(3) is bonded in a 9-coordinate geometry to two equivalent Nd(2), four equivalent Nd(1), one Si(1), and two equivalent Si(2) atoms. is represented by the CIF file [CIF]
