Y3Co3Ga crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 9-coordinate geometry to three equivalent Co(1), four equivalent Co(2), and two equivalent Ga(1) atoms. In the second Y site, Y(2) is bonded in a 9-coordinate geometry to two equivalent Co(1), four equivalent Co(2), and three equivalent Ga(1) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 9-coordinate geometry to three equivalent Y(1), four equivalent Y(2), and two equivalent Co(2) atoms. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to two equivalent Y(1), four equivalent Y(2), one Co(1), and two equivalent Ga(1) atoms. Ga(1) is bonded to two equivalent Y(1), six equivalent Y(2), and four equivalent Co(2) atoms to form a mixture of edge, corner, and face-sharing GaY8Co4 cuboctahedra.

In the first Y site, Y(1) is bonded in a 9-coordinate geometry to three equivalent Co(1), four equivalent Co(2), and two equivalent Ga(1) atoms. There are two shorter (2.84 Å) and one longer (3.03 Å) Y(1)-Co(1) bond length. All Y(1)-Co(2) bond lengths are 2.98 Å. Both Y(1)-Ga(1) bond lengths are 3.22 Å. In the second Y site, Y(2) is bonded in a 9-coordinate geometry to two equivalent Co(1), four equivalent Co(2), and three equivalent Ga(1) atoms. Both Y(2)-Co(1) bond lengths are 2.96 Å. There are a spread of Y(2)-Co(2) bond distances ranging from 2.86-2.94 Å. There is one shorter (3.19 Å) and two longer (3.22 Å) Y(2)-Ga(1) bond lengths. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 9-coordinate geometry to three equivalent Y(1), four equivalent Y(2), and two equivalent Co(2) atoms. Both Co(1)-Co(2) bond lengths are 2.29 Å. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to two equivalent Y(1), four equivalent Y(2), one Co(1), and two equivalent Ga(1) atoms. Both Co(2)-Ga(1) bond lengths are 2.54 Å. Ga(1) is bonded to two equivalent Y(1), six equivalent Y(2), and four equivalent Co(2) atoms to form a mixture of edge, corner, and face-sharing GaY8Co4 cuboctahedra.
