(Pt)16PtGa12 is Indium-derived structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three Pt clusters and three PtGa12 clusters. In each Pt cluster, there are five inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a distorted single-bond geometry to one Pt(3) atom. The Pt(1)-Pt(3) bond length is 1.42 Å. In the second Pt site, Pt(2) is bonded in a distorted single-bond geometry to one Pt(4) and one Pt(5) atom. The Pt(2)-Pt(4) bond length is 0.54 Å. The Pt(2)-Pt(5) bond length is 0.43 Å. In the third Pt site, Pt(3) is bonded in a single-bond geometry to one Pt(4) and two equivalent Pt(1) atoms. The Pt(3)-Pt(4) bond length is 0.47 Å. In the fourth Pt site, Pt(4) is bonded in a 2-coordinate geometry to one Pt(2) and one Pt(3) atom. In the fifth Pt site, Pt(5) is bonded in a trigonal non-coplanar geometry to three equivalent Pt(2) atoms. In each PtGa12 cluster, Pt(6) is bonded in a 3-coordinate geometry to three equivalent Ga(3) atoms. All Pt(6)-Ga(3) bond lengths are 0.48 Å. There are three inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a distorted water-like geometry to one Ga(1) and one Ga(2) atom. The Ga(1)-Ga(1) bond length is 1.55 Å. The Ga(1)-Ga(2) bond length is 1.43 Å. In the second Ga site, Ga(2) is bonded in a distorted single-bond geometry to one Ga(3) and two equivalent Ga(1) atoms. The Ga(2)-Ga(3) bond length is 1.22 Å. In the third Ga site, Ga(3) is bonded in a single-bond geometry to one Pt(6) and one Ga(2) atom.
