Materials Data on DySi3Rh5 by Materials Project
DyRh5Si3 crystallizes in the hexagonal P6_3/m space group. The structure is three-dimensional. Dy is bonded in a 12-coordinate geometry to six Rh and six Si atoms. There are two shorter (3.07 Å) and four longer (3.12 Å) Dy–Rh bond lengths. There are a spread of Dy–Si bond distances ranging from 3.07–3.10 Å. There are five inequivalent Rh sites. In the first Rh site, Rh is bonded in a distorted trigonal non-coplanar geometry to three equivalent Si atoms. There are one shorter (2.34 Å) and two longer (2.49 Å) Rh–Si bond lengths. In the second Rh site, Rh is bonded in a 4-coordinate geometry to two equivalent Dy and four Si atoms. There are a spread of Rh–Si bond distances ranging from 2.39–2.49 Å. In the third Rh site, Rh is bonded in a 4-coordinate geometry to two equivalent Dy and four Si atoms. There are a spread of Rh–Si bond distances ranging from 2.40–2.49 Å. In the fourth Rh site, Rh is bonded in a 4-coordinate geometry to two equivalent Dy and four Si atoms. There are a spread of Rh–Si bond distances ranging from 2.41–2.51 Å. In the fifth Rh site, Rh is bonded in a 5-coordinate geometry to five Si atoms. There are one shorter (2.37 Å) and four longer (2.52 Å) Rh–Si bond lengths. There are three inequivalent Si sites. In the first Si site, Si is bonded in a 10-coordinate geometry to two equivalent Dy and six Rh atoms. In the second Si site, Si is bonded in a 9-coordinate geometry to two equivalent Dy and seven Rh atoms. In the third Si site, Si is bonded in a 9-coordinate geometry to two equivalent Dy and seven Rh atoms.
