Iodine perchlorate
I have only found out that it exist but that is all information that I could find.
If you have any more information please post it.

From Handbook Of Inorganic Preparations by Brauer:
Iodine (III) Perchlorate
I(CIO4)3
I2 + 6 HClO4 + 3 O3 => 2 I(ClO4)3 + 3 H2O + 3 O2
Iodine (4 g.) and anhydrous HClO4 are precooled separately in
ice-salt baths and then mixed. A stream of O3 containing about 8%
ozone is introduced while the mixture is kept at 0°C. The gas
stream must be absolutely dry and the reaction flask carefully
protected against moisture (be careful in handling HClO4: organic
materials must not come in contact with it!). When the solution
assumes a transparent greenish color, treatment with O3 is
interrupted and the reaction vessel is left to cool for half an hour
in the ice-salt mixture. The greenish-yellow crystals are suctionfiltered
on a filter crucible protected from moisture by a CaCl2
tube and are washed with some cold, anhydrous HClO4.
PROPERTIES:
Extraordinarily moisture sensitive; even at room temperature
undergoes internal oxidation. Must therefore be kept cold.

The thread on ClO<sub>4</sub> mentions Iodine Perchlorate as one of the possible intermediates that display behavior that was at one time
attributed to the presence of ClO<Sub>4</sub>. Check it out as it is fairly interesting:

Would the I atom in this molecule be capable of accepting an e-pair? It is one pair short on electrons after all. Just like ICl3 is one pair short,
that dimerizes to form I2Cl6.

It is not short an electron pair. Draw the lewis dot and see. It has an Iodine atom with 3 Cl and 2 electron pairs. It can accept and electron pair
because I think it is a lewis acid because of the chlorines' electronegativity.

Could a mixture of I(CIO4)3 and Al be used as a flash powder or would that mixture be to unstable to use?
If yes I(CIO4)3 would be a good oxidiser since the whole molecule could be used instead of only oxigen in most of the other oxidisers.
The equation would be
3I(CIO4)3+26Al---11Al2O3+AlI3+3AlCl3

Too bad aluminum halides suck. I wonder if magesium would be moisture sensitive or even ignite on contact.
