Title: Materials Data on Eu2Zn2CuP3 by Materials Project

Abstract

Eu2CuZn2P3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Eu2+ is bonded to six P3- atoms to form EuP6 octahedra that share corners with six equivalent EuP6 octahedra, corners with six equivalent ZnP4 tetrahedra, edges with six equivalent EuP6 octahedra, edges with three equivalent ZnP4 tetrahedra, and a faceface with one EuP6 octahedra. The corner-sharing octahedral tilt angles are 45°. There are three shorter (2.99 Å) and three longer (3.11 Å) Eu–P bond lengths. Cu1+ is bonded in a trigonal planar geometry to three equivalent P3- atoms. All Cu–P bond lengths are 2.36 Å. Zn2+ is bonded to four equivalent P3- atoms to form ZnP4 tetrahedra that share corners with six equivalent EuP6 octahedra, corners with six equivalent ZnP4 tetrahedra, edges with three equivalent EuP6 octahedra, and edges with three equivalent ZnP4 tetrahedra. The corner-sharing octahedra tilt angles range from 21–52°. There are three shorter (2.47 Å) and one longer (2.55 Å) Zn–P bond lengths. There are two inequivalent P3- sites. In the first P3- site, P3- is bonded in a 3-coordinate geometry to six equivalent Eu2+ and three equivalent Cu1+ atoms. In the second P3- site, P3- is bonded to three equivalent Eu2+ and four equivalentmore » Zn2+ atoms to form distorted edge-sharing PEu3Zn4 pentagonal bipyramids.« less
