Materials Data on Nd2Co19Si3 by Materials Project
Abstract
Nd2Co19Si3 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Nd is bonded in a 8-coordinate geometry to nineteen Co atoms. There are a spread of Nd–Co bond distances ranging from 3.04–3.35 Å. There are six inequivalent Co sites. In the first Co site, Co is bonded in a 6-coordinate geometry to two equivalent Nd, nine Co, and three Si atoms. There are a spread of Co–Co bond distances ranging from 2.53–2.64 Å. All Co–Si bond lengths are 2.56 Å. In the second Co site, Co is bonded to two equivalent Nd, eight Co, and two Si atoms to form distorted CoNd2Co8Si2 cuboctahedra that share corners with eighteen CoNd2Co8Si2 cuboctahedra, edges with four CoNd2Co9Si cuboctahedra, and faces with twelve CoNd2Co8Si2 cuboctahedra. There are a spread of Co–Co bond distances ranging from 2.40–2.62 Å. There are one shorter (2.35 Å) and one longer (2.38 Å) Co–Si bond lengths. In the third Co site, Co is bonded to two equivalent Nd, nine Co, and one Si atom to form a mixture of distorted face, edge, and corner-sharing CoNd2Co9Si cuboctahedra. There are a spread of Co–Co bond distances ranging from 2.39–2.61 Å. The Co–Si bond length is 2.35 Å. In themore »
