The compound described by Y5Bi3 crystallizes in the orthorhombic Pnma space group. There are four inequivalent Y sites. In the first Y site, Y(1) is bonded in a 6-coordinate geometry to two equivalent Bi(1) and four equivalent Bi(2) atoms. In the second Y site, Y(2) is bonded to one Bi(1) and four equivalent Bi(2) atoms to form a mixture of distorted edge, face, and corner-sharing YBi5 trigonal bipyramids. In the third Y site, Y(3) is bonded in a 5-coordinate geometry to two equivalent Bi(1) and three equivalent Bi(2) atoms. In the fourth Y site, Y(4) is bonded to one Bi(1) and four equivalent Bi(2) atoms to form a mixture of distorted edge, face, and corner-sharing YBi5 square pyramids. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 8-coordinate geometry to one Y(2), one Y(4), two equivalent Y(1), and four equivalent Y(3) atoms. In the second Bi site, Bi(2) is bonded in a 9-coordinate geometry to two equivalent Y(1), two equivalent Y(2), two equivalent Y(4), and three equivalent Y(3) atoms. is represented by the CIF file [CIF]
