YHfTaPt crystallizes in the trigonal R3m space group. Y(1) is bonded in a single-bond geometry to four equivalent Hf(1), three equivalent Ta(1), and one Pt(1) atom. There are three shorter (2.84 Å) and one longer (3.42 Å) Y(1)-Hf(1) bond length. All Y(1)-Ta(1) bond lengths are 2.99 Å. The Y(1)-Pt(1) bond length is 1.58 Å. Hf(1) is bonded in a 11-coordinate geometry to four equivalent Y(1), four equivalent Ta(1), and three equivalent Pt(1) atoms. There are three shorter (2.84 Å) and one longer (3.42 Å) Hf(1)-Ta(1) bond length. All Hf(1)-Pt(1) bond lengths are 2.99 Å. Ta(1) is bonded in a 11-coordinate geometry to three equivalent Y(1), four equivalent Hf(1), and four equivalent Pt(1) atoms. There are three shorter (2.84 Å) and one longer (3.42 Å) Ta(1)-Pt(1) bond length. Pt(1) is bonded in a single-bond geometry to one Y(1), three equivalent Hf(1), and four equivalent Ta(1) atoms.
