VGa3(Ga)4 is alpha carbon monoxide-like structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three Ga clusters and three VGa3 clusters. In each Ga cluster, there are two inequivalent Ga sites. In the first Ga site, Ga(3) is bonded in a 3-coordinate geometry to three equivalent Ga(1) atoms. All Ga(3)-Ga(1) bond lengths are 0.24 Å. In the second Ga site, Ga(1) is bonded in a 2-coordinate geometry to one Ga(3) and two equivalent Ga(1) atoms. Both Ga(1)-Ga(1) bond lengths are 0.14 Å. In each VGa3 cluster, V(1) is bonded in a 3-coordinate geometry to three equivalent Ga(2) atoms. All V(1)-Ga(2) bond lengths are 0.24 Å. Ga(2) is bonded in a 2-coordinate geometry to one V(1) and two equivalent Ga(2) atoms. Both Ga(2)-Ga(2) bond lengths are 0.14 Å.
