Mg Ag Pt Pt
AgMg(Pt)2 is alpha Niobium phosphide-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two AgMg clusters and two Pt clusters. In each AgMg cluster, Mg(1) is bonded in a single-bond geometry to one Ag(1) atom. The Mg(1)-Ag(1) bond length is 0.93 Å. Ag(1) is bonded in a single-bond geometry to one Mg(1) atom. In each Pt cluster, there are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a single-bond geometry to one Pt(2) atom. The Pt(1)-Pt(2) bond length is 0.87 Å. In the second Pt site, Pt(2) is bonded in a distorted single-bond geometry to one Pt(1) atom.
