The crystal structure described by Yb5Bi3 crystallizes in the orthorhombic Pnma space group. There are four inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 5-coordinate geometry to two equivalent Bi(2) and three equivalent Bi(1) atoms. In the second Yb site, Yb(2) is bonded in a 5-coordinate geometry to two equivalent Bi(2) and four equivalent Bi(1) atoms. In the third Yb site, Yb(3) is bonded to one Bi(2) and four equivalent Bi(1) atoms to form distorted edge-sharing YbBi5 square pyramids. In the fourth Yb site, Yb(4) is bonded in a 5-coordinate geometry to one Bi(2) and four equivalent Bi(1) atoms. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 9-coordinate geometry to two equivalent Yb(2), two equivalent Yb(3), two equivalent Yb(4), and three equivalent Yb(1) atoms. In the second Bi site, Bi(2) is bonded in a 8-coordinate geometry to one Yb(3), one Yb(4), two equivalent Yb(2), and four equivalent Yb(1) atoms. is represented by the CIF card [CIF]
