La Bi Bi Bi Bi Os
LaOsBi4 crystallizes in the trigonal R3m space group. La(1) is bonded in a 10-coordinate geometry to four equivalent Os(1), three equivalent Bi(1), and three equivalent Bi(2) atoms. There are three shorter (3.89 Å) and one longer (3.91 Å) La(1)-Os(1) bond length. All La(1)-Bi(1) bond lengths are 3.42 Å. All La(1)-Bi(2) bond lengths are 3.74 Å. Os(1) is bonded in a 10-coordinate geometry to four equivalent La(1) and six equivalent Bi(1) atoms. There are three shorter (3.38 Å) and three longer (3.40 Å) Os(1)-Bi(1) bond lengths. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 6-coordinate geometry to one La(1), two equivalent Os(1), one Bi(2), and two equivalent Bi(1) atoms. The Bi(1)-Bi(2) bond length is 2.68 Å. Both Bi(1)-Bi(1) bond lengths are 1.55 Å. In the second Bi site, Bi(2) is bonded in a 6-coordinate geometry to three equivalent La(1) and three equivalent Bi(1) atoms.
