Structure du sulfur d'ytterbium, Yb2S3

The Yb atoms occupy independent, slightly distorted octahedral sites. All the metal sites are fully occupied. The structure consists of pairs of [YbS 6 ] octahedra forming chains parallel to the axis. In this direction, between two pairs of octahedra, there is an empty octahedral site. The compound may also be described as a layered structure; each layer is alternately composed of Yb and S atoms
