The material described by Yb4As2O is (La,Ba)CuO4 structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 6-coordinate geometry to five equivalent As(1) and one O(1) atom. In the second Yb site, Yb(2) is bonded in a linear geometry to four equivalent As(1) and two equivalent O(1) atoms. As(1) is bonded in a 9-coordinate geometry to four equivalent Yb(2) and five equivalent Yb(1) atoms. O(1) is bonded to two equivalent Yb(1) and four equivalent Yb(2) atoms to form corner-sharing OYb6 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF file [CIF]
