The crystal structure described by Yb5Ir3 crystallizes in the tetragonal P4/ncc space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded to two equivalent Ir(2) and three equivalent Ir(1) atoms to form distorted YbIr5 trigonal bipyramids that share corners with four equivalent Yb(2)Ir4 tetrahedra, corners with eleven equivalent Yb(1)Ir5 trigonal bipyramids,  an edgeedge with one Yb(2)Ir4 tetrahedra, edges with six equivalent Yb(1)Ir5 trigonal bipyramids, and faces with two equivalent Yb(1)Ir5 trigonal bipyramids. In the second Yb site, Yb(2) is bonded to four equivalent Ir(1) atoms to form YbIr4 tetrahedra that share corners with sixteen equivalent Yb(1)Ir5 trigonal bipyramids, edges with two equivalent Yb(2)Ir4 tetrahedra, and edges with four equivalent Yb(1)Ir5 trigonal bipyramids. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 8-coordinate geometry to two equivalent Yb(2) and six equivalent Yb(1) atoms. In the second Ir site, Ir(2) is bonded in a 8-coordinate geometry to eight equivalent Yb(1) atoms. is represented by the CIF file [CIF]
