HoPdGe2 crystallizes in the orthorhombic Cmcm space group. Ho(1) is bonded in a 14-coordinate geometry to four equivalent Pd(1), four equivalent Ge(2), and six equivalent Ge(1) atoms. Pd(1) is bonded in a 9-coordinate geometry to four equivalent Ho(1), one Ge(1), and four 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 six equivalent Ho(1), one Pd(1), and two equivalent Ge(1) atoms. In the second Ge site, Ge(2) is bonded to four equivalent Ho(1) and four equivalent Pd(1) atoms to form a mixture of distorted edge and face-sharing GeHo4Pd4 tetrahedra.
HoPdGe2 crystallizes in the orthorhombic Cmcm space group. Ho(1) is bonded in a 14-coordinate geometry to four equivalent Pd(1), four equivalent Ge(2), and six equivalent Ge(1) atoms. All Ho(1)-Pd(1) bond lengths are 3.17 Å. There are two shorter (3.34 Å) and two longer (3.55 Å) Ho(1)-Ge(2) bond lengths. There are four shorter (3.16 Å) and two longer (3.21 Å) Ho(1)-Ge(1) bond lengths. Pd(1) is bonded in a 9-coordinate geometry to four equivalent Ho(1), one Ge(1), and four equivalent Ge(2) atoms. The Pd(1)-Ge(1) bond length is 2.42 Å. There are two shorter (2.57 Å) and two longer (2.58 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 six equivalent Ho(1), one Pd(1), and two equivalent Ge(1) atoms. Both Ge(1)-Ge(1) bond lengths are 2.49 Å. In the second Ge site, Ge(2) is bonded to four equivalent Ho(1) and four equivalent Pd(1) atoms to form a mixture of distorted edge and face-sharing GeHo4Pd4 tetrahedra.
