Ag1Pt2 crystallizes in the triclinic P1 space group. There are four inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 5-coordinate geometry to one Pt(2), one Pt(4), two equivalent Pt(1), and one Ag(1) atom. The Pt(1)-Pt(2) bond length is 2.20 Å. The Pt(1)-Pt(4) bond length is 2.46 Å. Both Pt(1)-Pt(1) bond lengths are 2.77 Å. The Pt(1)-Ag(1) bond length is 3.20 Å. In the second Pt site, Pt(2) is bonded in a single-bond geometry to one Pt(1) and one Ag(2) atom. The Pt(2)-Ag(2) bond length is 0.94 Å. In the third Pt site, Pt(3) is bonded in a distorted T-shaped geometry to one Pt(4), one Ag(1), and one Ag(2) atom. The Pt(3)-Pt(4) bond length is 1.72 Å. The Pt(3)-Ag(1) bond length is 1.98 Å. The Pt(3)-Ag(2) bond length is 2.02 Å. In the fourth Pt site, Pt(4) is bonded in a 4-coordinate geometry to one Pt(1), one Pt(3), one Ag(1), and one Ag(2) atom. The Pt(4)-Ag(1) bond length is 2.50 Å. The Pt(4)-Ag(2) bond length is 2.59 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted single-bond geometry to one Pt(1), one Pt(3), and one Pt(4) atom. In the second Ag site, Ag(2) is bonded in a distorted single-bond geometry to one Pt(2), one Pt(3), and one Pt(4) atom.
