Abstract

The problem of the symmetry of the AlPO4-5 unit cell has been the subject of a variety of studies since the synthesis of this
material in 1982. The AlPO4-5 possesses a one-dimensional 12 membered channel, which is surrounded by 4- and 6-rings. The 12-
membered channel permits the adsorption of large molecules (e.g. hydrocarbons) and the use as catalysts. The substitution of
aluminum and phosphorous by transitions metal produces a new material, well known as metal-aluminophosphate or MeAPO-5
(Me = Mg, Co, Fe, Mn, V, etc.), containing acidic as well as redox sites. Although the numerous experimental and theoretical studies
about these materials a number of important questions does not has entirely established (for example, the amount, distribution and
occupation sites of metals in the framework).
