Yb3Pd4Ge4 crystallizes in the orthorhombic Immm space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded to two equivalent Ge(2) and four equivalent Ge(1) atoms to form distorted edge-sharing YbGe6 octahedra. In the second Yb site, Yb(2) is bonded in a 12-coordinate geometry to six equivalent Pd(1), two equivalent Ge(2), and four equivalent Ge(1) atoms. Pd(1) is bonded in a 7-coordinate geometry to three equivalent Yb(2), one Ge(1), and three 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 two equivalent Yb(1), four equivalent Yb(2), two equivalent Pd(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to one Yb(1), two equivalent Yb(2), and six equivalent Pd(1) atoms.

In the first Yb site, Yb(1) is bonded to two equivalent Ge(2) and four equivalent Ge(1) atoms to form distorted edge-sharing YbGe6 octahedra. Both Yb(1)-Ge(2) bond lengths are 3.03 Å. All Yb(1)-Ge(1) bond lengths are 3.10 Å. In the second Yb site, Yb(2) is bonded in a 12-coordinate geometry to six equivalent Pd(1), two equivalent Ge(2), and four equivalent Ge(1) atoms. There are four shorter (3.05 Å) and two longer (3.06 Å) Yb(2)-Pd(1) bond lengths. Both Yb(2)-Ge(2) bond lengths are 2.95 Å. All Yb(2)-Ge(1) bond lengths are 2.99 Å. Pd(1) is bonded in a 7-coordinate geometry to three equivalent Yb(2), one Ge(1), and three equivalent Ge(2) atoms. The Pd(1)-Ge(1) bond length is 2.55 Å. There is one shorter (2.57 Å) and two longer (2.59 Å) Pd(1)-Ge(2) bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Yb(1), four equivalent Yb(2), two equivalent Pd(1), and one Ge(1) atom. The Ge(1)-Ge(1) bond length is 2.50 Å.
