Materials Data on GdP by Materials Project

GdP is Halite, Rock Salt structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Gd3+ is bonded to six equivalent P3- atoms to form a mixture of edge and corner-sharing GdP6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Gd–P bond lengths are 2.86 Å. P3- is bonded to six equivalent Gd3+ atoms to form a mixture of edge and corner-sharing PGd6 octahedra. The corner-sharing octahedral tilt angles are 0°.

Materials Data on GdP5 by Materials Project

GdP5 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Gd3+ is bonded in a 8-coordinate geometry to eight P+0.60- atoms. There are a spread of Gd–P bond distances ranging from 2.97–3.01 Å. There are three inequivalent P+0.60- sites. In the first P+0.60- site, P+0.60- is bonded to one Gd3+ and three P+0.60- atoms to form distorted PGdP3 tetrahedra that share corners with nine PGd2P2 tetrahedra and an edgeedge with one PGdP3 tetrahedra. There are a spread of P–P bond distances ranging from 2.18–2.23 Å. In the second P+0.60- site, P+0.60- is bonded to two equivalent Gd3+ and two P+0.60- atoms to form PGd2P2 tetrahedra that share corners with fifteen PGdP3 tetrahedra and an edgeedge with one PGd2P2 tetrahedra. The P–P bond length is 2.23 Å. In the third P+0.60- site, P+0.60- is bonded to two equivalent Gd3+ and two equivalent P+0.60- atoms to form distorted corner-sharing PGd2P2 tetrahedra.
