Cu Cu Pd Pt
PtPdCu2 crystallizes in the triclinic P1 space group. Pt(1) is bonded in a 2-coordinate geometry to one Pd(1), two equivalent Cu(1), and two equivalent Cu(2) atoms. The Pt(1)-Pd(1) bond length is 0.99 Å. There is one shorter (2.44 Å) and one longer (2.79 Å) Pt(1)-Cu(1) bond length. There is one shorter (2.07 Å) and one longer (2.47 Å) Pt(1)-Cu(2) bond length. Pd(1) is bonded in a 1-coordinate geometry to one Pt(1), two equivalent Cu(1), and two equivalent Cu(2) atoms. There is one shorter (2.07 Å) and one longer (2.47 Å) Pd(1)-Cu(1) bond length. There is one shorter (2.44 Å) and one longer (2.79 Å) Pd(1)-Cu(2) bond length. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 8-coordinate geometry to two equivalent Pt(1), two equivalent Pd(1), two equivalent Cu(1), and two equivalent Cu(2) atoms. Both Cu(1)-Cu(1) bond lengths are 2.76 Å. There is one shorter (1.84 Å) and one longer (2.71 Å) Cu(1)-Cu(2) bond length. In the second Cu site, Cu(2) is bonded in a 8-coordinate geometry to two equivalent Pt(1), two equivalent Pd(1), two equivalent Cu(1), and two equivalent Cu(2) atoms. Both Cu(2)-Cu(2) bond lengths are 2.76 Å.
