Na17(In3Ga7)4Ga crystallizes in the cubic Fd-3m space group. The structure is three-dimensional and consists of eight gallium molecules and one Na17(In3Ga7)4 framework. In the Na17(In3Ga7)4 framework, there are three inequivalent Na sites. In the first Na site, Na is bonded in a 10-coordinate geometry to four equivalent In and six Ga atoms. There are two shorter (3.36 Å) and two longer (3.42 Å) Na–In bond lengths. There are a spread of Na–Ga bond distances ranging from 3.34–3.41 Å. In the second Na site, Na is bonded in a 12-coordinate geometry to three equivalent In and nine Ga atoms. All Na–In bond lengths are 3.44 Å. There are three shorter (3.20 Å) and six longer (3.27 Å) Na–Ga bond lengths. In the third Na site, Na is bonded in a 12-coordinate geometry to twelve equivalent Ga atoms. All Na–Ga bond lengths are 3.18 Å. In is bonded in a 11-coordinate geometry to five Na, three equivalent In, and three Ga atoms. There are one shorter (2.99 Å) and two longer (3.07 Å) In–In bond lengths. There are one shorter (2.90 Å) and two longer (3.33 Å) In–Ga bond lengths. There are three inequivalent Ga sites. In the first Ga site, Ga is bonded in a distorted q6 geometry to five Na, one In, and five Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.70–2.79 Å. In the second Ga site, Ga is bonded in a distorted q6 geometry to five Na and six Ga atoms. There are one shorter (2.65 Å) and two longer (2.76 Å) Ga–Ga bond lengths. In the third Ga site, Ga is bonded in a 1-coordinate geometry to six equivalent In and one Ga atom. The Ga–Ga bond length is 3.04 Å.
