Hf V Pt W
HfVWPt crystallizes in the trigonal R3m space group. Hf(1) is bonded in a 2-coordinate geometry to one V(1), one W(1), and three equivalent Pt(1) atoms. The Hf(1)-V(1) bond length is 2.17 Å. The Hf(1)-W(1) bond length is 2.25 Å. All Hf(1)-Pt(1) bond lengths are 2.71 Å. V(1) is bonded in a 2-coordinate geometry to one Hf(1) and four equivalent Pt(1) atoms. There is one shorter (2.25 Å) and three longer (2.99 Å) V(1)-Pt(1) bond lengths. W(1) is bonded in a distorted single-bond geometry to one Hf(1) and three equivalent Pt(1) atoms. All W(1)-Pt(1) bond lengths are 2.71 Å. Pt(1) is bonded in a 10-coordinate geometry to three equivalent Hf(1), four equivalent V(1), and three equivalent W(1) atoms.
