The material structure described by NdGeSi crystallizes in the orthorhombic Imma space group. Nd(1) is bonded to six equivalent Ge(1) and six equivalent Si(1) atoms to form a mixture of face and edge-sharing NdSi6Ge6 cuboctahedra. Ge(1) is bonded in a 9-coordinate geometry to six equivalent Nd(1), two equivalent Ge(1), and one Si(1) atom. Si(1) is bonded in a 9-coordinate geometry to six equivalent Nd(1), one Ge(1), and two equivalent Si(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
