YbMn2SbBi crystallizes in the trigonal P3m1 space group. Yb(1) is bonded to three equivalent Bi(1) and three equivalent Sb(1) atoms to form YbBi3Sb3 octahedra that share corners with six equivalent Mn(1)Bi3Sb tetrahedra, corners with six equivalent Mn(2)BiSb3 tetrahedra, edges with six equivalent Yb(1)Bi3Sb3 octahedra, edges with three equivalent Mn(1)Bi3Sb tetrahedra, and edges with three equivalent Mn(2)BiSb3 tetrahedra. There are two inequivalent Mn sites.
