Materials Data on Nd(AsPd)2 by Materials Project

Nd(PdAs)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Nd2+ is bonded in a distorted body-centered cubic geometry to eight equivalent As3- atoms. All Nd–As bond lengths are 3.29 Å. Pd2+ is bonded to four equivalent As3- atoms to form a mixture of edge and corner-sharing PdAs4 tetrahedra. All Pd–As bond lengths are 2.55 Å. As3- is bonded in a 9-coordinate geometry to four equivalent Nd2+, four equivalent Pd2+, and one As3- atom. The As–As bond length is 2.52 Å.

Materials Data on NdAsPd by Materials Project

NdPdAs is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. Nd is bonded to six equivalent Pd and six equivalent As atoms to form a mixture of edge and face-sharing NdAs6Pd6 cuboctahedra. There are three shorter (3.14 Å) and three longer (3.27 Å) Nd–Pd bond lengths. There are three shorter (3.14 Å) and three longer (3.27 Å) Nd–As bond lengths. Pd is bonded in a 9-coordinate geometry to six equivalent Nd and three equivalent As atoms. All Pd–As bond lengths are 2.54 Å. As is bonded in a 9-coordinate geometry to six equivalent Nd and three equivalent Pd atoms.
