BiReO4 crystallizes in the orthorhombic Cmcm space group. Re(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form corner-sharing ReO6 octahedra. The corner-sharing octahedral tilt angles range from 0-7°. Bi(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Re(1) and three equivalent Bi(1) atoms to form a mixture of corner and edge-sharing OReBi3 tetrahedra. In the second O site, O(2) is bonded in a linear geometry to two equivalent Re(1) atoms. In the third O site, O(3) is bonded in a linear geometry to two equivalent Re(1) atoms.

The corner-sharing octahedral tilt angles range from 0-7°. Both Re(1)-O(1) bond lengths are 2.03 Å. Both Re(1)-O(2) bond lengths are 1.87 Å. Both Re(1)-O(3) bond lengths are 1.93 Å. Bi(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. There are two shorter (2.26 Å) and four longer (2.42 Å) Bi(1)-O(1) bond lengths. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Re(1) and three equivalent Bi(1) atoms to form a mixture of corner and edge-sharing OReBi3 tetrahedra. In the second O site, O(2) is bonded in a linear geometry to two equivalent Re(1) atoms. In the third O site, O(3) is bonded in a linear geometry to two equivalent Re(1) atoms.
