Materials Data on Dy8In3Co by Materials Project

Abstract

Dy8CoIn3 crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. there are four inequivalent Dy sites. In the first Dy site, Dy is bonded in a 3-coordinate geometry to one Co and four equivalent In atoms. The Dy–Co bond length is 2.85 Å. There are two shorter (3.27 Å) and two longer (3.80 Å) Dy–In bond lengths. In the second Dy site, Dy is bonded in a 4-coordinate geometry to one Co and four equivalent In atoms. The Dy–Co bond length is 2.85 Å. There are a spread of Dy–In bond distances ranging from 3.09–3.76 Å. In the third Dy site, Dy is bonded to one Co and three equivalent In atoms to form distorted corner-sharing DyIn3Co tetrahedra. The corner-sharing octahedra tilt angles range from 13–48°. The Dy–Co bond length is 2.70 Å. All Dy–In bond lengths are 3.21 Å. In the fourth Dy site, Dy is bonded to six equivalent In atoms to form distorted DyIn6 octahedra that share corners with six equivalent DyIn3Co tetrahedra and faces with two equivalent DyIn6 octahedra. There are three shorter (3.40 Å) and three longer (3.46 Å) Dy–In bond lengths. Co is bonded in a 7-coordinate geometry to seven Dy atoms. In is bonded in a 11-coordinate geometry to eleven Dy atoms.
