Materials Data on Eu3Ni7B2 by Materials Project
Abstract
Eu3Ni7B2 crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. there are three inequivalent Eu sites. In the first Eu site, Eu is bonded in a distorted trigonal planar geometry to three equivalent Eu and three equivalent Ni atoms. All Eu–Eu bond lengths are 3.02 Å. All Eu–Ni bond lengths are 3.02 Å. In the second Eu site, Eu is bonded in a 12-coordinate geometry to twelve equivalent Ni and six B atoms. All Eu–Ni bond lengths are 2.94 Å. All Eu–B bond lengths are 3.02 Å. In the third Eu site, Eu is bonded to three equivalent Eu and nine Ni atoms to form distorted EuEu3Ni9 cuboctahedra that share corners with three equivalent NiEu6Ni6 cuboctahedra, edges with six equivalent EuEu3Ni9 cuboctahedra, and faces with three equivalent NiEu6Ni6 cuboctahedra. There are six shorter (2.76 Å) and three longer (3.02 Å) Eu–Ni bond lengths. There are two inequivalent Ni sites. In the first Ni site, Ni is bonded in a 2-coordinate geometry to three Eu, one Ni, and two B atoms. The Ni–Ni bond length is 2.71 Å. There are one shorter (1.99 Å) and one longer (2.06 Å) Ni–B bond lengths. In the second Ni site, Ni ismore »
