Cu Ge Pd Pd
Pd2CuGe crystallizes in the monoclinic Cm space group. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 1-coordinate geometry to one Cu(1) and three equivalent Ge(1) atoms. The Pd(1)-Cu(1) bond length is 1.86 Å. There is one shorter (2.17 Å) and two longer (2.81 Å) Pd(1)-Ge(1) bond lengths. In the second Pd site, Pd(2) is bonded in a 1-coordinate geometry to one Cu(1) and one Ge(1) atom. The Pd(2)-Cu(1) bond length is 1.92 Å. The Pd(2)-Ge(1) bond length is 2.30 Å. Cu(1) is bonded in a 2-coordinate geometry to one Pd(1), one Pd(2), and one Ge(1) atom. The Cu(1)-Ge(1) bond length is 2.76 Å. Ge(1) is bonded in a 5-coordinate geometry to one Pd(2), three equivalent Pd(1), and one Cu(1) atom.
