KPt2Ag crystallizes in the monoclinic Cm space group. K(1) is bonded in a single-bond geometry to one Pt(1) and one Pt(2) atom. The K(1)-Pt(1) bond length is 3.20 Å. The K(1)-Pt(2) bond length is 0.91 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a distorted linear geometry to one K(1) and one Ag(1) atom. The Pt(1)-Ag(1) bond length is 3.15 Å. In the second Pt site, Pt(2) is bonded in a single-bond geometry to one K(1) and one Ag(1) atom. The Pt(2)-Ag(1) bond length is 3.15 Å. Ag(1) is bonded to one Pt(1), one Pt(2), and six equivalent Ag(1) atoms to form a mixture of distorted edge and corner-sharing AgAg6Pt2 hexagonal bipyramids. All Ag(1)-Ag(1) bond lengths are 3.14 Å.
