Ti Hg Pd Pt
TiPtPdHg crystallizes in the trigonal R3m space group. Ti(1) is bonded in a distorted single-bond geometry to four equivalent Pt(1), one Pd(1), and three equivalent Hg(1) atoms. There is one shorter (2.63 Å) and three longer (2.86 Å) Ti(1)-Pt(1) bond lengths. The Ti(1)-Pd(1) bond length is 1.65 Å. All Ti(1)-Hg(1) bond lengths are 2.70 Å. Pt(1) is bonded in a 10-coordinate geometry to four equivalent Ti(1), three equivalent Pd(1), and three equivalent Hg(1) atoms. All Pt(1)-Pd(1) bond lengths are 2.70 Å. All Pt(1)-Hg(1) bond lengths are 2.70 Å. Pd(1) is bonded in a single-bond geometry to one Ti(1), three equivalent Pt(1), and four equivalent Hg(1) atoms. There is one shorter (2.63 Å) and three longer (2.86 Å) Pd(1)-Hg(1) bond lengths. Hg(1) is bonded in a 10-coordinate geometry to three equivalent Ti(1), three equivalent Pt(1), and four equivalent Pd(1) atoms.
