SrHfPtBi crystallizes in the trigonal R3m space group. Sr(1) is bonded in a 4-coordinate geometry to one Hf(1) and three equivalent Bi(1) atoms. The Sr(1)-Hf(1) bond length is 2.08 Å. All Sr(1)-Bi(1) bond lengths are 3.00 Å. Hf(1) is bonded to one Sr(1), three equivalent Pt(1), and one Bi(1) atom to form distorted HfSrBiPt3 trigonal bipyramids that share corners with six equivalent Hf(1)SrBiPt3 trigonal bipyramids and edges with three equivalent Bi(1)Sr3HfPt trigonal bipyramids. All Hf(1)-Pt(1) bond lengths are 3.00 Å. The Hf(1)-Bi(1) bond length is 2.08 Å. Pt(1) is bonded in a 4-coordinate geometry to three equivalent Hf(1) and one Bi(1) atom. The Pt(1)-Bi(1) bond length is 2.08 Å. Bi(1) is bonded to three equivalent Sr(1), one Hf(1), and one Pt(1) atom to form distorted BiSr3HfPt trigonal bipyramids that share corners with six equivalent Bi(1)Sr3HfPt trigonal bipyramids and edges with three equivalent Hf(1)SrBiPt3 trigonal bipyramids.
