Materials Data on Yb4Bi3 by Materials Project

Yb4Bi3 crystallizes in the cubic I-43d space group. The structure is three-dimensional. Yb is bonded to six equivalent Bi atoms to form a mixture of distorted edge, face, and corner-sharing YbBi6 octahedra. The corner-sharing octahedra tilt angles range from 17–50°. There are three shorter (3.25 Å) and three longer (3.43 Å) Yb–Bi bond lengths. Bi is bonded to eight equivalent Yb atoms to form a mixture of distorted edge, face, and corner-sharing BiYb8 hexagonal bipyramids.

Materials Data on YbBi2 by Materials Project

YbBi2 is Zirconium Disilicide structured and crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Yb is bonded in a 10-coordinate geometry to ten Bi atoms. There are a spread of Yb–Bi bond distances ranging from 3.35–3.67 Å. There are two inequivalent Bi sites. In the first Bi site, Bi is bonded in a 4-coordinate geometry to six equivalent Yb and two equivalent Bi atoms. Both Bi–Bi bond lengths are 3.21 Å. In the second Bi site, Bi is bonded in a 8-coordinate geometry to four equivalent Yb and four equivalent Bi atoms. All Bi–Bi bond lengths are 3.32 Å.
