Yb2PdGe3 is hexagonal omega structure-derived structured and crystallizes in the orthorhombic Pmm2 space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded to two equivalent Pd(1), two equivalent Ge(3), four equivalent Ge(1), and four equivalent Ge(2) atoms to form YbGe10Pd2 cuboctahedra that share edges with four equivalent Yb(1)Ge10Pd2 cuboctahedra, edges with eight equivalent Yb(2)Ge8Pd4 cuboctahedra, faces with four equivalent Yb(1)Ge10Pd2 cuboctahedra, and faces with four equivalent Yb(2)Ge8Pd4 cuboctahedra. In the second Yb site, Yb(2) is bonded to four equivalent Pd(1), two equivalent Ge(1), two equivalent Ge(2), and four equivalent Ge(3) atoms to form YbGe8Pd4 cuboctahedra that share edges with four equivalent Yb(2)Ge8Pd4 cuboctahedra, edges with eight equivalent Yb(1)Ge10Pd2 cuboctahedra, faces with four equivalent Yb(1)Ge10Pd2 cuboctahedra, and faces with four equivalent Yb(2)Ge8Pd4 cuboctahedra. Pd(1) is bonded in a 9-coordinate geometry to two equivalent Yb(1), four equivalent Yb(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 Yb(2), four equivalent Yb(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 Yb(2), four equivalent Yb(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 Yb(1), four equivalent Yb(2), one Pd(1), and two equivalent Ge(1) atoms.
