CrReO4 is beta Vanadium nitride-derived structured and crystallizes in the orthorhombic Cmmm 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 Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 46-47°. Re(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form ReO6 octahedra that share corners with eight equivalent Cr(1)O6 octahedra and edges with two equivalent Re(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 46-47°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Cr(1) and two equivalent Re(1) atoms. In the second O site, O(2) is bonded in a distorted T-shaped geometry to two equivalent Cr(1) and one Re(1) atom.
