BiRe2O6 crystallizes in the monoclinic C2/c space group. Re(1) is bonded to one O(3), two equivalent O(2), and three equivalent O(1) atoms to form a mixture of corner and edge-sharing ReO6 octahedra. The corner-sharing octahedral tilt angles range from 34-43°. Bi(1) is bonded in a 4-coordinate geometry to four equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to three equivalent Re(1) atoms. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Re(1) atoms. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Re(1) and two equivalent Bi(1) atoms.

The corner-sharing octahedral tilt angles range from 34-43°. The Re(1)-O(3) bond length is 1.98 Å. There is one shorter (1.94 Å) and one longer (1.95 Å) Re(1)-O(2) bond length. There are a spread of Re(1)-O(1) bond distances ranging from 1.96-2.03 Å. Bi(1) is bonded in a 4-coordinate geometry to four equivalent O(3) atoms. There are two shorter (2.15 Å) and two longer (2.29 Å) Bi(1)-O(3) bond lengths. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to three equivalent Re(1) atoms. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Re(1) atoms. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Re(1) and two equivalent Bi(1) atoms.
