Zn Ni Pt Pt
Pt2NiZn crystallizes in the triclinic P1 space group. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a distorted single-bond geometry to one Ni(1) and two equivalent Zn(1) atoms. The Pt(1)-Ni(1) bond length is 0.93 Å. There is one shorter (2.63 Å) and one longer (2.80 Å) Pt(1)-Zn(1) bond length. In the second Pt site, Pt(2) is bonded in a 2-coordinate geometry to one Ni(1) and one Zn(1) atom. The Pt(2)-Ni(1) bond length is 1.66 Å. The Pt(2)-Zn(1) bond length is 2.61 Å. Ni(1) is bonded in a 1-coordinate geometry to one Pt(1), one Pt(2), and one Zn(1) atom. The Ni(1)-Zn(1) bond length is 2.23 Å. Zn(1) is bonded in a 4-coordinate geometry to one Pt(2), two equivalent Pt(1), and one Ni(1) atom.
