The crystal structure described by Nd2RuFeSi2 crystallizes in the tetragonal P-4m2 space group. Nd(1) is bonded in a 9-coordinate geometry to two equivalent Ru(1), two equivalent Fe(1), and five equivalent Si(1) atoms. Ru(1) is bonded in a 12-coordinate geometry to four equivalent Nd(1), four equivalent Fe(1), and four equivalent Si(1) atoms. Fe(1) is bonded to four equivalent Nd(1), four equivalent Ru(1), and four equivalent Si(1) atoms to form a mixture of distorted corner and face-sharing FeNd4Si4Ru4 cuboctahedra. Si(1) is bonded in a 9-coordinate geometry to five equivalent Nd(1), two equivalent Ru(1), and two equivalent Fe(1) atoms. is represented by the CIF file [CIF]
