Materials Data on Dy3Ni2 by Materials Project

Abstract

Dy3Ni2 crystallizes in the monoclinic C2/m space group. The structure is two-dimensional and consists of one Dy3Ni2 sheet oriented in the (0, 0, 1) direction. there are three inequivalent Dy sites. In the first Dy site, Dy is bonded in a 4-coordinate geometry to four Ni atoms. There are two shorter (2.80 Å) and two longer (2.88 Å) Dy–Ni bond lengths. In the second Dy site, Dy is bonded in a distorted trigonal non-coplanar geometry to three Ni atoms. There are two shorter (2.77 Å) and one longer (2.78 Å) Dy–Ni bond lengths. In the third Dy site, Dy is bonded in a 7-coordinate geometry to seven Ni atoms. There are a spread of Dy–Ni bond distances ranging from 2.81–3.03 Å. There are two inequivalent Ni sites. In the first Ni site, Ni is bonded in a 7-coordinate geometry to seven Dy and one Ni atom. The Ni–Ni bond length is 2.68 Å. In the second Ni site, Ni is bonded in a 9-coordinate geometry to seven Dy and two Ni atoms. The Ni–Ni bond length is 2.66 Å.
