Materials Data on LaRe2Ag by Materials Project

Abstract

LaRe2Ag crystallizes in the cubic F-43m space group. The structure is three-dimensional. La is bonded in a distorted body-centered cubic geometry to ten Re and four equivalent Ag atoms. There are four shorter (2.93 Å) and six longer (3.38 Å) La–Re bond lengths. All La–Ag bond lengths are 2.93 Å. There are two inequivalent Re sites. In the first Re site, Re is bonded to four equivalent La and four equivalent Re atoms to form distorted edge-sharing ReLa4Re4 tetrahedra. All Re–Re bond lengths are 2.93 Å. In the second Re site, Re is bonded in a 4-coordinate geometry to six equivalent La, four equivalent Re, and four equivalent Ag atoms. All Re–Ag bond lengths are 2.93 Å. Ag is bonded in a distorted body-centered cubic geometry to four equivalent La and four equivalent Re atoms.
