Ti Bi Os Os Os Os
TiOs4Bi crystallizes in the trigonal R3m space group. Ti(1) is bonded in a distorted single-bond geometry to three equivalent Os(1) and one Bi(1) atom. All Ti(1)-Os(1) bond lengths are 2.89 Å. The Ti(1)-Bi(1) bond length is 1.73 Å. There are two inequivalent Os sites. In the first Os site, Os(2) is bonded in a 3-coordinate geometry to three equivalent Os(1) atoms. All Os(2)-Os(1) bond lengths are 1.15 Å. In the second Os site, Os(1) is bonded in a 5-coordinate geometry to one Ti(1), one Os(2), two equivalent Os(1), and one Bi(1) atom. Both Os(1)-Os(1) bond lengths are 0.67 Å. The Os(1)-Bi(1) bond length is 1.51 Å. Bi(1) is bonded in a distorted single-bond geometry to one Ti(1) and three equivalent Os(1) atoms.
