NaRe2Ga crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NaRe2Ga clusters. Na(1) is bonded in a distorted single-bond geometry to one Re(2) atom. The Na(1)-Re(2) bond length is 2.61 Å. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a 2-coordinate geometry to one Re(2) and one Ga(1) atom. The Re(1)-Re(2) bond length is 1.06 Å. The Re(1)-Ga(1) bond length is 1.35 Å. In the second Re site, Re(2) is bonded in a 2-coordinate geometry to one Na(1), one Re(1), and one Ga(1) atom. The Re(2)-Ga(1) bond length is 1.35 Å. Ga(1) is bonded in a 2-coordinate geometry to one Re(1) and one Re(2) atom.
