Cr(ReO3)2 is beta Vanadium nitride-derived structured and crystallizes in the tetragonal P4_2/mnm space group. Cr(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form CrO6 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 41-51°. 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 Cr(1)O6 octahedra, corners with four equivalent Re(1)O6 octahedra,  an edgeedge with one Cr(1)O6 octahedra, and  an edgeedge with one Re(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 41-51°. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted T-shaped geometry to one Cr(1) and two equivalent Re(1) atoms. In the second O site, O(1) is bonded in a 3-coordinate geometry to one Cr(1) and two equivalent Re(1) atoms.

Cr(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form CrO6 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 41-51°. Both Cr(1)-O(1) bond lengths are 1.90 Å. All Cr(1)-O(2) bond lengths are 2.01 Å. 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 Cr(1)O6 octahedra, corners with four equivalent Re(1)O6 octahedra,  an edgeedge with one Cr(1)O6 octahedra, and  an edgeedge with one Re(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 41-51°. Both Re(1)-O(1) bond lengths are 1.97 Å. There are two shorter (2.02 Å) and two longer (2.04 Å) Re(1)-O(2) bond lengths. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted T-shaped geometry to one Cr(1) and two equivalent Re(1) atoms. In the second O site, O(1) is bonded in a 3-coordinate geometry to one Cr(1) and two equivalent Re(1) atoms.
