Materials Data on Yb(NdS2)2 by Materials Project

Yb(NdS2)2 crystallizes in the orthorhombic C222_1 space group. The structure is three-dimensional. Yb2+ is bonded in a distorted rectangular see-saw-like geometry to four S2- atoms. There are two shorter (2.68 Å) and two longer (2.75 Å) Yb–S bond lengths. Nd3+ is bonded to five S2- atoms to form edge-sharing NdS5 square pyramids. There are a spread of Nd–S bond distances ranging from 2.71–2.95 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a rectangular see-saw-like geometry to one Yb2+ and three equivalent Nd3+ atoms. In the second S2- site, S2- is bonded in a distorted T-shaped geometry to one Yb2+ and two equivalent Nd3+ atoms.
