In the fourteenth S2- site, S2- is bonded to four Yb+2.44+ and one Fe3+ atom to form distorted edge-sharing SYb4Fe square pyramids. In the fifteenth S2- site, S2- is bonded to three Yb+2.44+ and two Fe3+ atoms to form distorted SYb3Fe2 square pyramids that share a cornercorner with one SYb3Fe2 square pyramid and an edgeedge with one SYb4Fe square pyramid. In the sixteenth S2- site, S2- is bonded in a 3-coordinate geometry to two Yb+2.44+ and one Fe3+ atom. In the seventeenth S2- site, S2- is bonded in a see-saw-like geometry to three Yb+2.44+ and one Fe3+ atom. In the eighteenth S2- site, S2- is bonded in a distorted rectangular see-saw-like geometry to two Yb+2.44+ and two Fe3+ atoms. In the nineteenth S2- site, S2- is bonded in a rectangular see-saw-like geometry to four Yb+2.44+ atoms. In the twentieth S2- site, S2- is bonded to three Yb+2.44+ and two Fe3+ atoms to form distorted SYb3Fe2 square pyramids that share a cornercorner with one SYb3Fe2 square pyramid, edges with two equivalent SYb4Fe square pyramids, and a faceface with one SYb3F},
