Materials Data on RbGa7 by Materials Project

RbGa7 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Rb is bonded in a 9-coordinate geometry to fifteen Ga atoms. There are a spread of Rb–Ga bond distances ranging from 3.77–3.93 Å. There are three inequivalent Ga sites. In the first Ga site, Ga is bonded in a 8-coordinate geometry to one Rb and seven Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.57–2.83 Å. In the second Ga site, Ga is bonded in a 7-coordinate geometry to three equivalent Rb and four Ga atoms. There are one shorter (2.56 Å) and three longer (2.62 Å) Ga–Ga bond lengths. In the third Ga site, Ga is bonded in a 9-coordinate geometry to three equivalent Rb and six Ga atoms. Both Ga–Ga bond lengths are 2.83 Å.

Materials Data on Rb3Ga by Materials Project

(Rb)3Ga is alpha bismuth trifluoride structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional and consists of two gallium molecules and one Rb framework. In the Rb framework, there are two inequivalent Rb sites. In the first Rb site, Rb is bonded in a 12-coordinate geometry to four equivalent Rb atoms. All Rb–Rb bond lengths are 4.21 Å. In the second Rb site, Rb is bonded in a distorted body-centered cubic geometry to eight equivalent Rb atoms.
