PtCuP2 crystallizes in the triclinic P1 space group. Pt(1) is bonded in a distorted single-bond geometry to one Cu(1), one P(2), and two equivalent P(1) atoms. The Pt(1)-Cu(1) bond length is 1.51 Å. The Pt(1)-P(2) bond length is 2.50 Å. There is one shorter (2.12 Å) and one longer (2.66 Å) Pt(1)-P(1) bond length. Cu(1) is bonded in a 2-coordinate geometry to one Pt(1), two equivalent P(1), and two equivalent P(2) atoms. There is one shorter (2.50 Å) and one longer (2.98 Å) Cu(1)-P(1) bond length. There is one shorter (2.12 Å) and one longer (2.66 Å) Cu(1)-P(2) bond length. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 5-coordinate geometry to two equivalent Pt(1), two equivalent Cu(1), and one P(2) atom. The P(1)-P(2) bond length is 1.45 Å. In the second P site, P(2) is bonded in a 4-coordinate geometry to one Pt(1), two equivalent Cu(1), and one P(1) atom.
