Materials Data on TaReSi by Materials Project

TaReSi crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Ta is bonded in a 11-coordinate geometry to six equivalent Re and five Si atoms. There are two shorter (2.86 Å) and four longer (2.94 Å) Ta–Re bond lengths. There are four shorter (2.67 Å) and one longer (2.77 Å) Ta–Si bond lengths. Re is bonded in a 10-coordinate geometry to six equivalent Ta and four Si atoms. There are two shorter (2.43 Å) and two longer (2.59 Å) Re–Si bond lengths. There are two inequivalent Si sites. In the first Si site, Si is bonded in a 9-coordinate geometry to three equivalent Ta and six equivalent Re atoms. In the second Si site, Si is bonded in a 9-coordinate geometry to six equivalent Ta and three equivalent Re atoms.

Materials Data on TaReSi by Materials Project

TaReSi crystallizes in the orthorhombic Ima2 space group. The structure is three-dimensional. there are three inequivalent Ta sites. In the first Ta site, Ta is bonded in a 11-coordinate geometry to six Re and five Si atoms. There are a spread of Ta–Re bond distances ranging from 2.79–2.88 Å. There are a spread of Ta–Si bond distances ranging from 2.66–2.97 Å. In the second Ta site, Ta is bonded in a 5-coordinate geometry to six Re and five Si atoms. There are a spread of Ta–Re bond distances ranging from 2.91–3.20 Å. There are three shorter (2.65 Å) and two longer (2.70 Å) Ta–Si bond lengths. In the third Ta site, Ta is bonded in a 9-coordinate geometry to six Re and five Si atoms. There are four shorter (2.87 Å) and two longer (3.12 Å) Ta–Re bond lengths. There are two shorter (2.67 Å) and three longer (2.69 Å) Ta–Si bond lengths. There are two inequivalent Re sites. In the first Re site, Re is bonded in a 12-coordinate geometry to six Ta, two equivalent Re, and four Si atoms. Both Re–Re bond lengths are 2.94 Å. There are two shorter (2.52 Å) and two longer (2.57 Å) Re–Si bond lengths. In the second Re site, Re is bonded in a 8-coordinate geometry to six Ta, three Re, and four Si atoms. There are one shorter (2.98 Å) and one longer (3.03 Å) Re–Re bond lengths. There are a spread of Re–Si bond distances ranging from 2.43–2.55 Å. There are two inequivalent Si sites. In the first Si site, Si is bonded in a 9-coordinate geometry to three Ta and six Re atoms. In the second Si site, Si is bonded in a 9-coordinate geometry to six Ta and three Re atoms.
