Hg Pt Rh W
WRhPtHg crystallizes in the trigonal R3m space group. W(1) is bonded in a 10-coordinate geometry to three equivalent Rh(1), three equivalent Pt(1), and four equivalent Hg(1) atoms. All W(1)-Rh(1) bond lengths are 2.70 Å. All W(1)-Pt(1) bond lengths are 2.70 Å. There is one shorter (2.45 Å) and three longer (2.92 Å) W(1)-Hg(1) bond lengths. Rh(1) is bonded in a single-bond geometry to three equivalent W(1), one Pt(1), and one Hg(1) atom. The Rh(1)-Pt(1) bond length is 2.45 Å. The Rh(1)-Hg(1) bond length is 1.90 Å. Pt(1) is bonded in a 7-coordinate geometry to three equivalent W(1), one Rh(1), and three equivalent Hg(1) atoms. All Pt(1)-Hg(1) bond lengths are 2.70 Å. Hg(1) is bonded in a 1-coordinate geometry to four equivalent W(1), one Rh(1), and three equivalent Pt(1) atoms.
