Title: Materials Data on Sm(ZnP)3 by Materials Project

Abstract

Zn3SmP3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Sm3+ is bonded to six equivalent P3- atoms to form SmP6 octahedra that share corners with six equivalent ZnP4 tetrahedra, edges with six equivalent SmP6 octahedra, and edges with six equivalent ZnP4 tetrahedra. All Sm–P bond lengths are 2.90 Å. There are two inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded in a trigonal planar geometry to three equivalent P3- atoms. All Zn–P bond lengths are 2.33 Å. In the second Zn2+ site, Zn2+ is bonded to four P3- atoms to form ZnP4 tetrahedra that share corners with three equivalent SmP6 octahedra, corners with seven equivalent ZnP4 tetrahedra, and edges with three equivalent SmP6 octahedra. The corner-sharing octahedral tilt angles are 16°. There are one shorter (2.42 Å) and three longer (2.48 Å) Zn–P bond lengths. There are two inequivalent P3- sites. In the first P3- site, P3- is bonded to five Zn2+ atoms to form PZn5 trigonal bipyramids that share corners with six equivalent PSm3Zn3 octahedra and corners with six equivalent PZn5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 70°. In the second P3- site, P3- is bonded to three equivalent Sm3+ andmore » three equivalent Zn2+ atoms to form PSm3Zn3 octahedra that share corners with three equivalent PSm3Zn3 octahedra, corners with three equivalent PZn5 trigonal bipyramids, and edges with nine equivalent PSm3Zn3 octahedra. The corner-sharing octahedral tilt angles are 0°.« less
