CoRe2O6 is beta Vanadium nitride-derived structured and crystallizes in the tetragonal P4_2/mnm space group. Re(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form ReO6 octahedra that share corners with four equivalent Re(1)O6 octahedra, corners with four equivalent Co(1)O6 octahedra,  an edgeedge with one Re(1)O6 octahedra, and  an edgeedge with one Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 39-52°. Co(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form CoO6 octahedra that share corners with eight equivalent Re(1)O6 octahedra and edges with two equivalent Re(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-52°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to two equivalent Re(1) and one Co(1) atom. In the second O site, O(2) is bonded in a distorted T-shaped geometry to two equivalent Re(1) and one Co(1) atom.

The corner-sharing octahedral tilt angles range from 39-52°. Both Re(1)-O(1) bond lengths are 1.97 Å. There are two shorter (1.95 Å) and two longer (2.03 Å) Re(1)-O(2) bond lengths. Co(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form CoO6 octahedra that share corners with eight equivalent Re(1)O6 octahedra and edges with two equivalent Re(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-52°. Both Co(1)-O(1) bond lengths are 1.90 Å. All Co(1)-O(2) bond lengths are 2.08 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to two equivalent Re(1) and one Co(1) atom. In the second O site, O(2) is bonded in a distorted T-shaped geometry to two equivalent Re(1) and one Co(1) atom.
