Ag Bi Pt
PtAgBi crystallizes in the trigonal R3m space group. Pt(1) is bonded in a hexagonal planar geometry to three equivalent Ag(1) and three equivalent Bi(1) atoms. All Pt(1)-Ag(1) bond lengths are 2.69 Å. All Pt(1)-Bi(1) bond lengths are 2.69 Å. Ag(1) is bonded to three equivalent Pt(1) and four equivalent Bi(1) atoms to form distorted AgBi4Pt3 hexagonal pyramids that share corners with three equivalent Bi(1)Ag4Pt3 hexagonal pyramids, corners with six equivalent Ag(1)Bi4Pt3 hexagonal pyramids, edges with three equivalent Bi(1)Ag4Pt3 hexagonal pyramids, and edges with six equivalent Ag(1)Bi4Pt3 hexagonal pyramids. There are three shorter (2.78 Å) and one longer (2.98 Å) Ag(1)-Bi(1) bond length. Bi(1) is bonded to three equivalent Pt(1) and four equivalent Ag(1) atoms to form distorted BiAg4Pt3 hexagonal pyramids that share corners with three equivalent Ag(1)Bi4Pt3 hexagonal pyramids, corners with six equivalent Bi(1)Ag4Pt3 hexagonal pyramids, edges with three equivalent Ag(1)Bi4Pt3 hexagonal pyramids, and edges with six equivalent Bi(1)Ag4Pt3 hexagonal pyramids.
