N2 - Single crystals of a three dimensional ammonium aluminophosphate (PSU-3) have been synthesized as a minor phase in the synthesis of the unknown cyclohexylamine templated ALPO structure UHM-5, and its structure determined by single crystal X-ray diffraction analysis. The material of composition: NH 4·Al 2(OH) (PO 4) 2· 2H 2O crystallizes in the monoclinic space group P2(1)/n with a = 9.597 ; b = 9.553 ; c = 9.957 ; β = 103.74°. The pore structure comprises a spiral 8-ring pore down the b-axis intersecting with a linear pore down the c-axis; a linear 12-ring pore is parallel to the a-axis. The pores are filled with water, ammonium ions and projecting Al-OH 2 groups. Infra-red microscopy showed ammonium but no occlusion of organics in the structure, which like the UHM-5 structure, degrades at ∼300 °C. A parallel gallophosphate experiment produced only a UHM-5 like product.
