Materials Data on GaRe by Materials Project

ReGa crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Re is bonded to six equivalent Re and six equivalent Ga atoms to form distorted ReGa6Re6 cuboctahedra that share corners with eighteen equivalent ReGa6Re6 cuboctahedra, edges with six equivalent ReGa6Re6 cuboctahedra, edges with twelve equivalent GaGa6Re6 cuboctahedra, faces with eight equivalent ReGa6Re6 cuboctahedra, and faces with twelve equivalent GaGa6Re6 cuboctahedra. All Re–Re bond lengths are 2.89 Å. All Re–Ga bond lengths are 2.65 Å.

Materials Data on Ga3Re by Materials Project

Ga3Re crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. Re is bonded in a 9-coordinate geometry to one Re and eight Ga atoms. The Re–Re bond length is 2.67 Å. There are a spread of Re–Ga bond distances ranging from 2.52–2.67 Å. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded in a distorted linear geometry to two equivalent Re atoms. In the second Ga site, Ga is bonded in a 1-coordinate geometry to three equivalent Re atoms.
