SrPtNiZn crystallizes in the trigonal R3m space group. Sr(1) is bonded in a single-bond geometry to four equivalent Pt(1), one Ni(1), and three equivalent Zn(1) atoms. There are three shorter (2.72 Å) and one longer (3.69 Å) Sr(1)-Pt(1) bond length. The Sr(1)-Ni(1) bond length is 0.22 Å. All Sr(1)-Zn(1) bond lengths are 2.71 Å. Pt(1) is bonded in a 10-coordinate geometry to four equivalent Sr(1), three equivalent Ni(1), and three equivalent Zn(1) atoms. All Pt(1)-Ni(1) bond lengths are 2.71 Å. All Pt(1)-Zn(1) bond lengths are 2.71 Å. Ni(1) is bonded in a single-bond geometry to one Sr(1), three equivalent Pt(1), and three equivalent Zn(1) atoms. All Ni(1)-Zn(1) bond lengths are 2.72 Å. Zn(1) is bonded in a 9-coordinate geometry to three equivalent Sr(1), three equivalent Pt(1), and three equivalent Ni(1) atoms.
