Cr2O5 crystallizes in the orthorhombic Pbam space group. Cr(1) is bonded in a 5-coordinate geometry to one O(3), two equivalent O(1), and two equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Cr(1) atoms. In the second O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent Cr(1) atoms. In the third O site, O(3) is bonded in a linear geometry to two equivalent Cr(1) atoms.
Cr2O5 crystallizes in the orthorhombic Pbam space group. Cr(1) is bonded in a 5-coordinate geometry to one O(3), two equivalent O(1), and two equivalent O(2) atoms. The Cr(1)-O(3) bond length is 1.78 Å. Both Cr(1)-O(1) bond lengths are 1.80 Å. There is one shorter (1.66 Å) and one longer (2.16 Å) Cr(1)-O(2) bond length. There are three inequivalent O sites. In the first O site, O(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Cr(1) atoms. In the second O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent Cr(1) atoms. In the third O site, O(3) is bonded in a linear geometry to two equivalent Cr(1) atoms.
