Abstract
Yb11(Sm2S11)2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are six inequivalent Yb+2.91+ sites. In the first Yb+2.91+ site, Yb+2.91+ is bonded to six S2- atoms to form a mixture of distorted edge and corner-sharing YbS6 pentagonal pyramids. The corner-sharing octahedra tilt angles range from 61–69°. There are a spread of Yb–S bond distances ranging from 2.72–2.97 Å. In the second Yb+2.91+ site, Yb+2.91+ is bonded in a 6-coordinate geometry to six S2- atoms. There are a spread of Yb–S bond distances ranging from 2.71–3.36 Å. In the third Yb+2.91+ site, Yb+2.91+ is bonded to six S2- atoms to form distorted YbS6 square pyramids that share a cornercorner with one SYb3Sm2S octahedra, corners with three equivalent YbS6 octahedra, corners with two equivalent YbS6 pentagonal pyramids, corners with two equivalent YbS5 square pyramids, and edges with two equivalent YbS6 square pyramids. The corner-sharing octahedra tilt angles range from 28–70°. There are a spread of Yb–S bond distances ranging from 2.63–3.46 Å. In the fourth Yb+2.91+ site, Yb+2.91+ is bonded to six S2- atoms to form a mixture of edge and corner-sharing YbS6 octahedra. There are a spread of Yb–S bond distances ranging from 2.67–3.10 Å.
