The material structure described by Y5Re2O12 crystallizes in the monoclinic C2/m space group. There are three inequivalent Y sites. In the first Y site, Y(1) is bonded in a 7-coordinate geometry to one O(2), two equivalent O(3), and four equivalent O(4) atoms. In the second Y site, Y(2) is bonded to one O(2), two equivalent O(4), and four equivalent O(3) atoms to form distorted YO7 pentagonal bipyramids that share corners with two equivalent Y(3)O6 octahedra,  an edgeedge with one Y(3)O6 octahedra, edges with two equivalent Re(1)O6 octahedra, and edges with two equivalent Y(2)O7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 56°. In the third Y site, Y(3) is bonded to two equivalent O(1) and four equivalent O(3) atoms to form YO6 octahedra that share corners with four equivalent Re(1)O6 octahedra, corners with four equivalent Y(2)O7 pentagonal bipyramids, and edges with two equivalent Y(2)O7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 38°. Re(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form ReO6 octahedra that share corners with two equivalent Y(3)O6 octahedra, edges with two equivalent Re(1)O6 octahedra, and edges with two equivalent Y(2)O7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 38°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Y(3) and two equivalent Re(1) atoms.
