Materials Data on NdSiNi by Materials Project
NdNiSi crystallizes in the tetragonal I4_1md space group. The structure is three-dimensional. Nd3+ is bonded to six equivalent Si4- atoms to form a mixture of distorted face, edge, and corner-sharing NdSi6 pentagonal pyramids. There are four shorter (3.11 Å) and two longer (3.12 Å) Nd–Si bond lengths. Ni1+ is bonded in a trigonal planar geometry to three equivalent Si4- atoms. All Ni–Si bond lengths are 2.34 Å. Si4- is bonded in a 9-coordinate geometry to six equivalent Nd3+ and three equivalent Ni1+ atoms.
