Materials Data on Nd2MgS4 by Materials Project
Abstract
MgNd2S4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Mg2+ is bonded to five S2- atoms to form MgS5 square pyramids that share corners with four NdS6 octahedra, edges with four NdS6 octahedra, and edges with four equivalent MgS5 square pyramids. The corner-sharing octahedra tilt angles range from 5–6°. There are a spread of Mg–S bond distances ranging from 2.53–2.67 Å. There are two inequivalent Nd3+ sites. In the first Nd3+ site, Nd3+ is bonded to six S2- atoms to form NdS6 octahedra that share corners with three equivalent NdS6 octahedra, corners with two equivalent MgS5 square pyramids, edges with six NdS6 octahedra, and an edgeedge with one MgS5 square pyramid. The corner-sharing octahedra tilt angles range from 54–60°. There are a spread of Nd–S bond distances ranging from 2.78–2.92 Å. In the second Nd3+ site, Nd3+ is bonded to six S2- atoms to form NdS6 octahedra that share corners with three equivalent NdS6 octahedra, corners with two equivalent MgS5 square pyramids, edges with four NdS6 octahedra, and edges with three equivalent MgS5 square pyramids. The corner-sharing octahedra tilt angles range from 54–60°. There are a spread of Nd–S bond distances ranging from 2.73–2.97 Å. There aremore »

In the second S2- site, S2- is bonded in a rectangular see-saw-like geometry to four Nd3+ atoms. In the third S2- site, S2- is bonded in a 3-coordinate geometry to three Nd3+ atoms. In the fourth S2- site, S2- is bonded to two equivalent Mg2+ and three Nd3+ atoms to form SNd3Mg2 square pyramids that share corners with two equivalent SNd2Mg3 square pyramids and edges with five SNd3Mg2 square pyramids.},
