Materials Data on Nd2Co12P7 by Materials Project
Abstract
Nd2Co12P7 crystallizes in the monoclinic Pm space group. The structure is three-dimensional. there are two inequivalent Nd3+ sites. In the first Nd3+ site, Nd3+ is bonded to six P3- atoms to form distorted NdP6 pentagonal pyramids that share corners with twelve CoP4 tetrahedra, edges with twelve CoP4 tetrahedra, and faces with two equivalent NdP6 pentagonal pyramids. There are four shorter (2.91 Å) and two longer (2.92 Å) Nd–P bond lengths. In the second Nd3+ site, Nd3+ is bonded to six P3- atoms to form distorted NdP6 pentagonal pyramids that share corners with twelve CoP4 tetrahedra, edges with nine CoP4 tetrahedra, and faces with two equivalent NdP6 pentagonal pyramids. All Nd–P bond lengths are 2.89 Å. There are eleven inequivalent Co+1.25+ sites. In the first Co+1.25+ site, Co+1.25+ is bonded to four P3- atoms to form CoP4 tetrahedra that share corners with two equivalent NdP6 pentagonal pyramids, corners with twelve CoP4 tetrahedra, edges with three NdP6 pentagonal pyramids, and edges with three CoP4 tetrahedra. There are three shorter (2.29 Å) and one longer (2.30 Å) Co–P bond lengths. In the second Co+1.25+ site, Co+1.25+ is bonded to four P3- atoms to form CoP4 tetrahedra that share corners with two equivalent NdP6more »
