K Ni Pt Au
KPtNiAu crystallizes in the trigonal R3m space group. K(1) is bonded in a single-bond geometry to three equivalent Pt(1), one Ni(1), and four equivalent Au(1) atoms. All K(1)-Pt(1) bond lengths are 2.73 Å. The K(1)-Ni(1) bond length is 0.19 Å. There are three shorter (2.73 Å) and one longer (3.80 Å) K(1)-Au(1) bond length. Pt(1) is bonded in a distorted q6 geometry to three equivalent K(1), three equivalent Ni(1), and three equivalent Au(1) atoms. All Pt(1)-Ni(1) bond lengths are 2.73 Å. All Pt(1)-Au(1) bond lengths are 2.73 Å. Ni(1) is bonded in a single-bond geometry to one K(1), three equivalent Pt(1), and three equivalent Au(1) atoms. All Ni(1)-Au(1) bond lengths are 2.73 Å. Au(1) is bonded in a distorted q6 geometry to four equivalent K(1), three equivalent Pt(1), and three equivalent Ni(1) atoms.
