Iodine pentoxide

Iodine pentoxide is the chemical compound with the formula I2O5. This iodine oxide is the anhydride of iodic acid, and the only stable oxide of iodine. It is produced by dehydrating iodic acid at 200 °C in a stream of dry air: Iodine pentoxide is the chemical compound with the formula I2O5. This iodine oxide is the anhydride of iodic acid, and the only stable oxide of iodine. It is produced by dehydrating iodic acid at 200 °C in a stream of dry air: I2O5 is bent with an I-O-I angle of 139.2°, but the molecule has no mirror plane so its symmetry is C2 rather than C2v. The terminal I-O distances are around 1.80 Å and the bridging I-O distances are around 1.95 Å. Iodine pentoxide easily oxidises carbon monoxide to carbon dioxide at room temperature:
