Ba2Pd5Ge4 crystallizes in the orthorhombic Cmce space group. Ba(1) is bonded in a 7-coordinate geometry to one Pd(3), two equivalent Pd(1), two equivalent Pd(2), and two equivalent Ge(1) atoms. There are three inequivalent Pd sites. In the first Pd site, Pd(3) is bonded in a 6-coordinate geometry to two equivalent Ba(1) and four equivalent Ge(1) atoms. In the second Pd site, Pd(1) is bonded in a 6-coordinate geometry to two equivalent Ba(1) and four equivalent Ge(1) atoms. In the third Pd site, Pd(2) is bonded in a 4-coordinate geometry to two equivalent Ba(1) and four equivalent Ge(1) atoms. Ge(1) is bonded in a 6-coordinate geometry to one Ba(1), one Pd(3), two equivalent Pd(1), and two equivalent Pd(2) atoms.
Ba2Pd5Ge4 crystallizes in the orthorhombic Cmce space group. Ba(1) is bonded in a 7-coordinate geometry to one Pd(3), two equivalent Pd(1), two equivalent Pd(2), and two equivalent Ge(1) atoms. The Ba(1)-Pd(3) bond length is 3.43 Å. Both Ba(1)-Pd(1) bond lengths are 3.30 Å. Both Ba(1)-Pd(2) bond lengths are 3.51 Å. Both Ba(1)-Ge(1) bond lengths are 3.41 Å. There are three inequivalent Pd sites. In the first Pd site, Pd(3) is bonded in a 6-coordinate geometry to two equivalent Ba(1) and four equivalent Ge(1) atoms. All Pd(3)-Ge(1) bond lengths are 2.61 Å. In the second Pd site, Pd(1) is bonded in a 6-coordinate geometry to two equivalent Ba(1) and four equivalent Ge(1) atoms. There are two shorter (2.52 Å) and two longer (2.59 Å) Pd(1)-Ge(1) bond lengths. In the third Pd site, Pd(2) is bonded in a 4-coordinate geometry to two equivalent Ba(1) and four equivalent Ge(1) atoms. There are two shorter (2.50 Å) and two longer (2.58 Å) Pd(2)-Ge(1) bond lengths. Ge(1) is bonded in a 6-coordinate geometry to one Ba(1), one Pd(3), two equivalent Pd(1), and two equivalent Pd(2) atoms.
