Materials Data on ScRe2 by Materials Project

ScRe2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Sc is bonded in a 12-coordinate geometry to twelve Re atoms. There are a spread of Sc–Re bond distances ranging from 3.07–3.11 Å. There are two inequivalent Re sites. In the first Re site, Re is bonded to six equivalent Sc and six equivalent Re atoms to form a mixture of face, edge, and corner-sharing ReSc6Re6 cuboctahedra. All Re–Re bond lengths are 2.67 Å. In the second Re site, Re is bonded to six equivalent Sc and six Re atoms to form a mixture of face, edge, and corner-sharing ReSc6Re6 cuboctahedra. There are two shorter (2.57 Å) and two longer (2.73 Å) Re–Re bond lengths.

Materials Data on Sc5Re24 by Materials Project

Sc5Re24 crystallizes in the cubic I-43m space group. The structure is three-dimensional. there are two inequivalent Sc sites. In the first Sc site, Sc is bonded in a 3-coordinate geometry to one Sc and fifteen Re atoms. The Sc–Sc bond length is 3.10 Å. There are a spread of Sc–Re bond distances ranging from 2.79–3.26 Å. In the second Sc site, Sc is bonded in a 12-coordinate geometry to four equivalent Sc and twelve equivalent Re atoms. All Sc–Re bond lengths are 3.06 Å. There are two inequivalent Re sites. In the first Re site, Re is bonded to four Sc and eight Re atoms to form a mixture of distorted face, edge, and corner-sharing ReSc4Re8 cuboctahedra. There are a spread of Re–Re bond distances ranging from 2.55–2.89 Å. In the second Re site, Re is bonded in a 1-coordinate geometry to two equivalent Sc and eleven Re atoms. There are two shorter (2.83 Å) and four longer (2.94 Å) Re–Re bond lengths.
