Na Na Ga Re
Na2ReGa crystallizes in the monoclinic Cm space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded to six equivalent Na(1), one Re(1), and one Ga(1) atom to form a mixture of distorted corner and edge-sharing NaNa6GaRe hexagonal bipyramids. All Na(1)-Na(1) bond lengths are 2.89 Å. The Na(1)-Re(1) bond length is 3.72 Å. The Na(1)-Ga(1) bond length is 3.01 Å. In the second Na site, Na(2) is bonded in a single-bond geometry to one Re(1) and one Ga(1) atom. The Na(2)-Re(1) bond length is 1.13 Å. The Na(2)-Ga(1) bond length is 2.82 Å. Re(1) is bonded in a single-bond geometry to one Na(1) and one Na(2) atom. Ga(1) is bonded in a distorted linear geometry to one Na(1) and one Na(2) atom.
