Materials Data on Yb(ZnP)2 by Materials Project

Abstract

Yb(ZnP)2 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Yb2+ is bonded to six equivalent P3- atoms to form YbP6 octahedra that share corners with twelve equivalent ZnP4 tetrahedra, edges with six equivalent YbP6 octahedra, and edges with six equivalent ZnP4 tetrahedra. All Yb–P bond lengths are 2.91 Å. Zn2+ is bonded to four equivalent P3- atoms to form ZnP4 tetrahedra that share corners with six equivalent YbP6 octahedra, corners with six equivalent ZnP4 tetrahedra, edges with three equivalent YbP6 octahedra, and edges with three equivalent ZnP4 tetrahedra. The corner-sharing octahedra tilt angles range from 20–53°. There are three shorter (2.43 Å) and one longer (2.55 Å) Zn–P bond lengths. P3- is bonded to three equivalent Yb2+ and four equivalent Zn2+ atoms to form a mixture of distorted corner and edge-sharing PYb3Zn4 pentagonal bipyramids.
