Ti Si Ag Hg
TiAgHgSi crystallizes in the trigonal R3m space group. Ti(1) is bonded in a single-bond geometry to four equivalent Ag(1), three equivalent Hg(1), and one Si(1) atom. There are three shorter (2.72 Å) and one longer (3.39 Å) Ti(1)-Ag(1) bond length. All Ti(1)-Hg(1) bond lengths are 2.70 Å. The Ti(1)-Si(1) bond length is 0.63 Å. Ag(1) is bonded in a distorted q6 geometry to four equivalent Ti(1), three equivalent Hg(1), and three equivalent Si(1) atoms. All Ag(1)-Hg(1) bond lengths are 2.70 Å. All Ag(1)-Si(1) bond lengths are 2.70 Å. Hg(1) is bonded in a distorted q6 geometry to three equivalent Ti(1), three equivalent Ag(1), and three equivalent Si(1) atoms. All Hg(1)-Si(1) bond lengths are 2.72 Å. Si(1) is bonded in a single-bond geometry to one Ti(1), three equivalent Ag(1), and three equivalent Hg(1) atoms.
