Materials Data on DyNiSn2 by Materials Project
DyNiSn2 is delta Molybdenum Boride-derived structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are three inequivalent Dy sites. In the first Dy site, Dy is bonded in a 8-coordinate geometry to six Ni and eight Sn atoms. There are a spread of Dy–Ni bond distances ranging from 3.28–3.46 Å. There are a spread of Dy–Sn bond distances ranging from 3.13–3.20 Å. In the second Dy site, Dy is bonded in a 11-coordinate geometry to two equivalent Ni and nine Sn atoms. Both Dy–Ni bond lengths are 3.09 Å. There are a spread of Dy–Sn bond distances ranging from 3.15–3.49 Å. In the third Dy site, Dy is bonded in a 1-coordinate geometry to four Ni and nine Sn atoms. There are two shorter (3.14 Å) and two longer (3.24 Å) Dy–Ni bond lengths. There are a spread of Dy–Sn bond distances ranging from 3.17–3.59 Å. There are three inequivalent Ni sites. In the first Ni site, Ni is bonded in a 7-coordinate geometry to three Dy and five Sn atoms. There are a spread of Ni–Sn bond distances ranging from 2.50–2.78 Å. In the second Ni site, Ni is bonded in a 10-coordinate geometry to four Dy and five Sn atoms. There are a spread of Ni–Sn bond distances ranging from 2.54–2.67 Å. In the third Ni site, Ni is bonded in a 10-coordinate geometry to five Dy and five Sn atoms. There are a spread of Ni–Sn bond distances ranging from 2.54–2.74 Å. There are six inequivalent Sn sites. In the first Sn site, Sn is bonded in a 8-coordinate geometry to four Dy, three Ni, and one Sn atom. The Sn–Sn bond length is 3.01 Å. In the second Sn site, Sn is bonded in a 2-coordinate geometry to four Dy, one Ni, and four Sn atoms. There are two shorter (3.01 Å) and two longer (3.27 Å) Sn–Sn bond lengths. In the third Sn site, Sn is bonded in a 8-coordinate geometry to four Dy, three equivalent Ni, and one Sn atom. In the fourth Sn site, Sn is bonded in a 9-coordinate geometry to six Dy and three Ni atoms. In the fifth Sn site, Sn is bonded in a 6-coordinate geometry to four Dy and two Ni atoms. In the sixth Sn site, Sn is bonded in a 7-coordinate geometry to four Dy, three Ni, and two equivalent Sn atoms.
