Gd3InO6 is Spinel-like structured and crystallizes in the trigonal R-3 space group. Gd(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form distorted GdO6 pentagonal pyramids that share  a cornercorner with one In(1)O6 octahedra,  a cornercorner with one In(2)O6 octahedra, corners with four equivalent Gd(1)O6 pentagonal pyramids,  an edgeedge with one In(1)O6 octahedra,  an edgeedge with one In(2)O6 octahedra, and edges with four equivalent Gd(1)O6 pentagonal pyramids. The corner-sharing octahedral tilt angles range from 38-49°. There are two inequivalent In sites. In the first In site, In(1) is bonded to six equivalent O(1) atoms to form InO6 octahedra that share corners with six equivalent Gd(1)O6 pentagonal pyramids and edges with six equivalent Gd(1)O6 pentagonal pyramids. In the second In site, In(2) is bonded to six equivalent O(2) atoms to form InO6 octahedra that share corners with six equivalent Gd(1)O6 pentagonal pyramids and edges with six equivalent Gd(1)O6 pentagonal pyramids. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Gd(1) and one In(1) atom to form a mixture of edge and corner-sharing OGd3In trigonal pyramids. In the second O site, O(2) is bonded in a distorted see-saw-like geometry to three equivalent Gd(1) and one In(2) atom.

The corner-sharing octahedral tilt angles range from 38-49°. There are a spread of Gd(1)-O(1) bond distances ranging from 2.25-2.38 Å. There is one shorter (2.29 Å) and two longer (2.33 Å) Gd(1)-O(2) bond lengths. There are two inequivalent In sites. In the first In site, In(1) is bonded to six equivalent O(1) atoms to form InO6 octahedra that share corners with six equivalent Gd(1)O6 pentagonal pyramids and edges with six equivalent Gd(1)O6 pentagonal pyramids. All In(1)-O(1) bond lengths are 2.21 Å. In the second In site, In(2) is bonded to six equivalent O(2) atoms to form InO6 octahedra that share corners with six equivalent Gd(1)O6 pentagonal pyramids and edges with six equivalent Gd(1)O6 pentagonal pyramids. All In(2)-O(2) bond lengths are 2.17 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Gd(1) and one In(1) atom to form a mixture of edge and corner-sharing OGd3In trigonal pyramids. In the second O site, O(2) is bonded in a distorted see-saw-like geometry to three equivalent Gd(1) and one In(2) atom.
