The material structure described by YbMnSb2 is Parent of FeAs superconductors-derived structured and crystallizes in the tetragonal I4/mmm space group. Yb(1) is bonded to four equivalent Mn(1), four equivalent Sb(1), and four equivalent Sb(2) atoms to form distorted YbMn4Sb8 cuboctahedra that share corners with eight equivalent Yb(1)Mn4Sb8 cuboctahedra, corners with eight equivalent Mn(1)Yb4Sb4 tetrahedra, edges with four equivalent Yb(1)Mn4Sb8 cuboctahedra, edges with four equivalent Mn(1)Yb4Sb4 tetrahedra, and faces with five equivalent Yb(1)Mn4Sb8 cuboctahedra. Mn(1) is bonded to four equivalent Yb(1) and four equivalent Sb(1) atoms to form distorted MnYb4Sb4 tetrahedra that share corners with eight equivalent Yb(1)Mn4Sb8 cuboctahedra, edges with four equivalent Yb(1)Mn4Sb8 cuboctahedra, edges with four equivalent Mn(1)Yb4Sb4 tetrahedra, and faces with four equivalent Mn(1)Yb4Sb4 tetrahedra. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 8-coordinate geometry to four equivalent Yb(1) and four equivalent Mn(1) atoms. In the second Sb site, Sb(2) is bonded in a 8-coordinate geometry to four equivalent Yb(1) and four equivalent Sb(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
