description: Bi20(PtI12)3 is alpha Niobium phosphide-derived structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one Bi20(PtI12)3 cluster. there are two inequivalent Pt2- sites. In the first Pt2- site, Pt2- is bonded in an octahedral geometry to six Bi+2.10+ atoms. There are four shorter (2.76 Å) and two longer (2.77 Å) Pt–Bi bond lengths. In the second Pt2- site, Pt2- is bonded in an octahedral geometry to six Bi+2.10+ atoms. There are a spread of Pt–Bi bond distances ranging from 2.76–2.78 Å. There are ten inequivalent Bi+2.10+ sites. In the first Bi+2.10+ site, Bi+2.10+ is bonded to one Pt2- and four I1- atoms to form BiPtI4 square pyramids that share a cornercorner with one BiPtI4 square pyramid, an edgeedge with one BiI6 octahedra, and edges with four BiPtI4 square pyramids. There are a spread of Bi–I bond distances ranging from 3.10–3.28 Å. In the second Bi+2.10+ site, Bi+2.10+ is bonded to one Pt2- and four I1- atoms to form BiPtI4 square pyramids that share a cornercorner with one BiPtI4 square pyramid, an edgeedge with one BiI6 octahedra, and edges with four BiPtI4 square pyramids. There are two shorter (3.11 Å) and two longer (3.28 Å) Bi–I bond lengths. In the third Bi+2.10+ site, Bi+2.10+ is bonded to one Pt2- and four I1- atoms to form BiPtI4 square pyramids that share a cornercorner with one BiPtI4 square pyramid, an edgeedge with one BiI6 octahedra, and edges with four BiPtI4 square pyramids. There are a spread of Bi–I bond distances ranging from 3.03–3.42 Å.

There are a spread of Bi–I bond distances ranging from 3.05–3.21 Å. In the eighth Bi+2.10+ site, Bi+2.10+ is bonded to one Pt2- and four I1- atoms to form BiPtI4 square pyramids that share a cornercorner with one BiPtI4 square pyramid, an edgeedge with one BiI6 octahedra, and edges with four BiPtI4 square pyramids. There are a spread of Bi–I bond distances ranging from 3.10–3.28 Å. In the ninth Bi+2.10+ site, Bi+2.10+ is bonded to one Pt2- and four I1- atoms to form BiPtI4 square pyramids that share a cornercorner with one BiPtI4 square pyramid, an edgeedge with one BiI6 octahedra, and edges with four BiPtI4 square pyramids. There are a spread of Bi–I bond distances ranging from 3.03–3.41 Å. In the tenth Bi+2.10+ site, Bi+2.10+ is bonded to one Pt2- and four I1- atoms to form a mixture of corner and edge-sharing BiPtI4 square pyramids. There are a spread of Bi–I bond distances ranging from 3.08–3.26 Å. There are eighteen inequivalent I1- sites.
