YbGa6Te10 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. Yb2+ is bonded to six Te2- atoms to form distorted YbTe6 octahedra that share corners with two equivalent YbTe6 octahedra, corners with four GaTe4 tetrahedra, and edges with four GaTe4 tetrahedra.

In the first Ga3+ site, Ga3+ is bonded to four Te2- atoms to form GaTe4 tetrahedra that share corners with six GaTe4 tetrahedra and an edgeedge with one YbTe6 octahedra. There are a spread of Ga–Te bond distances ranging from 2.65–2.73 Å. In the second Ga3+ site, Ga3+ is bonded to four Te2- atoms to form GaTe4 tetrahedra that share a cornercorner with one YbTe6 octahedra and corners with six GaTe4 tetrahedra. The corner-sharing octahedral tilt angles are 69°. There are a spread of Ga–Te bond distances ranging from 2.61–2.73 Å. In the third Ga3+ site, Ga3+ is bonded to four Te2- atoms to form GaTe4 tetrahedra that share a cornercorner with one YbTe6 octahedra, corners with four GaTe4 tetrahedra, an edgeedge with one YbTe6 octahedra, and an edgeedge with one GaTe4 tetrahedra. The corner-sharing octahedral tilt angles are 59°. There are a spread of Ga–Te bond distances ranging from 2.64–2.69 Å. In the fourth Ga3+ site, Ga3+ is bonded to four Te2- atoms to form GaTe4 tetrahedra that share corners with four GaTe4 tetrahedra, an edgeedge with one YbTe6 octahedra, and an edgeedge with one GaTe4 tetrahedra. There are a spread of Ga–Te bond distances ranging from 2.63–2.72 Å. In the fifth Ga3+ site, Ga3+ is bonded to four Te2- atoms to form GaTe4 tetrahedra that share a cornercorner with one YbTe6 octahedra, corners with four GaTe4 tetrahedra, and an edgeedge with one GaTe4 tetrahedra. The corner-sharing octahedral tilt angles are 58°. There are a spread of Ga–Te bond distances ranging from 2.60–2.73 Å. In the sixth Ga3+ site, Ga3+ is bonded to four Te2- atoms to form GaTe4 tetrahedra that share a cornercorner with one YbTe6 octahedra, corners with six GaTe4 tetrahedra, and an edgeedge with one YbTe6 octahedra. The corner-sharing octahedral tilt angles are 69°. There are a spread of Ga–Te bond distances ranging from 2.65–2.71 Å. There are eleven inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a distorted trigonal non-coplanar geometry to three Ga3+ atoms. In the second Te2- site, Te2- is bonded in an L-shaped geometry to two Ga3+ atoms. In the third Te2- site, Te2- is bonded in a 3-coordinate geometry to one Yb2+ and two Ga3+ atoms. In the fourth Te2- site, Te2- is bonded in a 3-coordinate geometry to three Ga3+ atoms. In the fifth Te2- site, Te2- is bonded in a 3-coordinate geometry to three Ga3+ atoms. In the sixth Te2- site, Te2- is bonded in a 3-coordinate geometry to one Yb2+ and two Ga3+ atoms. In the seventh Te2- site, Te2- is bonded in a 4-coordinate geometry to two equivalent Yb2+ and two equivalent Ga3+ atoms. In the eighth Te2- site, Te2- is bonded in a 4-coordinate geometry to two equivalent Yb2+ and two equivalent Ga3+ atoms. In the ninth Te2- site, Te2- is bonded in a 3-coordinate geometry to three Ga3+ atoms. In the tenth Te2- site, Te2- is bonded in a distorted trigonal non-coplanar geometry to one Yb2+ and two Ga3+ atoms. In the eleventh Te2- site, Te2- is bonded in a 3-coordinate geometry to one Yb2+ and two Ga3+ atoms.
