The material described by Nd3(RhGe)2 crystallizes in the orthorhombic Pbcm space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 9-coordinate geometry to four equivalent Rh(1), two equivalent Ge(2), and three equivalent Ge(1) atoms. In the second Nd site, Nd(2) is bonded in a 7-coordinate geometry to four equivalent Rh(1), two equivalent Ge(1), and three equivalent Ge(2) atoms. Rh(1) is bonded in a 9-coordinate geometry to two equivalent Nd(1), four equivalent Nd(2), one Ge(1), and two equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to three equivalent Nd(1), four equivalent Nd(2), and two equivalent Rh(1) atoms. In the second Ge site, Ge(2) is bonded to two equivalent Nd(1), six equivalent Nd(2), and four equivalent Rh(1) atoms to form a mixture of distorted corner, face, and edge-sharing GeNd8Rh4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
