Nd2PdGe3 is hexagonal omega structure-derived structured and crystallizes in the orthorhombic Pmm2 space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded to two equivalent Pd(1), two equivalent Ge(3), four equivalent Ge(1), and four equivalent Ge(2) atoms to form NdGe10Pd2 cuboctahedra that share edges with four equivalent Nd(1)Ge10Pd2 cuboctahedra, edges with eight equivalent Nd(2)Ge8Pd4 cuboctahedra, faces with four equivalent Nd(1)Ge10Pd2 cuboctahedra, and faces with four equivalent Nd(2)Ge8Pd4 cuboctahedra. In the second Nd site, Nd(2) is bonded to four equivalent Pd(1), two equivalent Ge(1), two equivalent Ge(2), and four equivalent Ge(3) atoms to form NdGe8Pd4 cuboctahedra that share edges with four equivalent Nd(2)Ge8Pd4 cuboctahedra, edges with eight equivalent Nd(1)Ge10Pd2 cuboctahedra, faces with four equivalent Nd(1)Ge10Pd2 cuboctahedra, and faces with four equivalent Nd(2)Ge8Pd4 cuboctahedra. Pd(1) is bonded in a 9-coordinate geometry to two equivalent Nd(1), four equivalent Nd(2), one Ge(3), and two equivalent Ge(2) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Nd(2), four equivalent Nd(1), one Ge(2), and two equivalent Ge(3) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Nd(2), four equivalent Nd(1), two equivalent Pd(1), and one Ge(1) atom. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to two equivalent Nd(1), four equivalent Nd(2), one Pd(1), and two equivalent Ge(1) atoms.
