Materials Data on Re2Si by Materials Project

Abstract

Re2Si crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are four inequivalent Re sites. In the first Re site, Re is bonded in a 11-coordinate geometry to eight Re and three Si atoms. There are a spread of Re–Re bond distances ranging from 2.65–2.89 Å. There are a spread of Re–Si bond distances ranging from 2.54–2.82 Å. In the second Re site, Re is bonded in a 10-coordinate geometry to six Re and four Si atoms. There are a spread of Re–Re bond distances ranging from 2.56–2.76 Å. There are a spread of Re–Si bond distances ranging from 2.50–2.83 Å. In the third Re site, Re is bonded in a 11-coordinate geometry to six Re and five Si atoms. There are one shorter (2.65 Å) and two longer (2.81 Å) Re–Re bond lengths. There are a spread of Re–Si bond distances ranging from 2.42–3.03 Å. In the fourth Re site, Re is bonded in a 10-coordinate geometry to six Re and four Si atoms. There are a spread of Re–Si bond distances ranging from 2.48–2.67 Å. There are two inequivalent Si sites. In the first Si site, Si is bonded in a 9-coordinate geometry to eight Re and one Si atom. The Si–Si bond length is 2.81 Å. In the second Si site, Si is bonded in a 10-coordinate geometry to eight Re and two Si atoms. The Si–Si bond length is 2.87 Å.
