Er2(RhGa3)3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Er is bonded in a 11-coordinate geometry to eleven Ga atoms. There are a spread of Er–Ga bond distances ranging from 3.01–3.14 Å. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 8-coordinate geometry to eight Ga atoms. There are a spread of Rh–Ga bond distances ranging from 2.57–2.65 Å. In the second Rh site, Rh is bonded in a 8-coordinate geometry to eight Ga atoms. There are a spread of Rh–Ga bond distances ranging from 2.56–2.64 Å. There are four inequivalent Ga sites. In the first Ga site, Ga is bonded in a 2-coordinate geometry to two equivalent Er, two equivalent Rh, and six Ga atoms. There are four shorter (2.75 Å) and two longer (2.78 Å) Ga–Ga bond lengths. In the second Ga site, Ga is bonded in a 3-coordinate geometry to three equivalent Er, three Rh, and five Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.77–2.95 Å. In the third Ga site, Ga is bonded in a 3-coordinate geometry to two equivalent Er, three Rh, and five Ga atoms. All Ga–Ga bond lengths are 2.81 Å. In the fourth Ga site, Ga is bonded in a 10-coordinate geometry to two equivalent Er, two equivalent Rh, and six Ga atoms. The Ga–Ga bond length is 2.74 Å.
