Nd2(IrGe)3 crystallizes in the tetragonal P4/mmm space group. Nd(1) is bonded to four equivalent Nd(1), one Ir(1), and one Ge(1) atom to form distorted NdNd4GeIr octahedra that share corners with four equivalent Nd(1)Nd4GeIr octahedra, edges with four equivalent Nd(1)Nd4GeIr octahedra, and edges with four equivalent Ge(1)NdGe4Ir octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a distorted linear geometry to one Nd(1) and one Ge(2) atom. In the second Ir site, Ir(2) is bonded in a distorted linear geometry to two equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to one Nd(1), one Ir(2), and four equivalent Ge(1) atoms to form distorted GeNdGe4Ir octahedra that share corners with five equivalent Ge(1)NdGe4Ir octahedra, edges with four equivalent Nd(1)Nd4GeIr octahedra, and edges with four equivalent Ge(1)NdGe4Ir octahedra. The corner-sharing octahedra are not tilted. In the second Ge site, Ge(2) is bonded in a distorted linear geometry to two equivalent Ir(1) atoms.
