Title: Materials Data on Yb2FeS4 by Materials Project

Abstract

FeYb2S4 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are eight inequivalent Yb+2.50+ sites. In the first Yb+2.50+ site, Yb+2.50+ is bonded to six S2- atoms to form YbS6 octahedra that share corners with six FeS4 tetrahedra and edges with six YbS6 octahedra. There are four shorter (2.79 Å) and two longer (2.81 Å) Yb–S bond lengths. In the second Yb+2.50+ site, Yb+2.50+ is bonded to six S2- atoms to form YbS6 octahedra that share corners with six FeS4 tetrahedra and edges with six YbS6 octahedra. There are a spread of Yb–S bond distances ranging from 2.79–2.81 Å.
