Materials Data on YRh5 by Materials Project

YRh5 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Y is bonded in a distorted hexagonal planar geometry to eighteen Rh atoms. There are six shorter (3.03 Å) and twelve longer (3.40 Å) Y–Rh bond lengths. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 12-coordinate geometry to three equivalent Y and nine Rh atoms. There are six shorter (2.64 Å) and three longer (3.03 Å) Rh–Rh bond lengths. In the second Rh site, Rh is bonded to four equivalent Y and eight Rh atoms to form a mixture of edge, face, and corner-sharing RhY4Rh8 cuboctahedra. All Rh–Rh bond lengths are 2.63 Å.

Materials Data on YRh3 by Materials Project

Rh3Y crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Y sites. In the first Y site, Y is bonded in a 12-coordinate geometry to twelve Rh atoms. There are a spread of Y–Rh bond distances ranging from 3.02–3.32 Å. In the second Y site, Y is bonded in a distorted hexagonal planar geometry to eighteen Rh atoms. There are six shorter (3.04 Å) and twelve longer (3.42 Å) Y–Rh bond lengths. There are four inequivalent Rh sites. In the first Rh site, Rh is bonded to five Y and seven Rh atoms to form a mixture of distorted face, edge, and corner-sharing RhY5Rh7 cuboctahedra. There are a spread of Rh–Rh bond distances ranging from 2.63–2.69 Å. In the second Rh site, Rh is bonded in a 12-coordinate geometry to three equivalent Y and nine Rh atoms. All Rh–Rh bond lengths are 3.04 Å. In the third Rh site, Rh is bonded in a 12-coordinate geometry to three equivalent Y and nine Rh atoms. In the fourth Rh site, Rh is bonded to six equivalent Y and six equivalent Rh atoms to form RhY6Rh6 cuboctahedra that share corners with twelve equivalent RhY5Rh7 cuboctahedra, edges with six equivalent RhY6Rh6 cuboctahedra, and faces with eighteen equivalent RhY5Rh7 cuboctahedra.
