Materials Data on Nd3Se4 by Materials Project
Nd3Se4 crystallizes in the cubic I-43d space group. The structure is three-dimensional. Nd+2.67+ is bonded to eight equivalent Se2- atoms to form a mixture of distorted face, edge, and corner-sharing NdSe8 hexagonal bipyramids. There are four shorter (3.02 Å) and four longer (3.18 Å) Nd–Se bond lengths. Se2- is bonded to six equivalent Nd+2.67+ atoms to form a mixture of distorted face, edge, and corner-sharing SeNd6 octahedra. The corner-sharing octahedra tilt angles range from 17–50°.
