 AlPO4.2H2O was crystallized from amorphous AlPO4 treated at 160 Celsius degrees during 8 days in a closed teflon vessel.
 Amorphous AlPO4 was precipitated from a solution of AlPO4 in H3PO4 10% by neutralization with NH4OH.
 This monoclinic phase lose crystallization water between 130 Celsius degrees and 400 Celsius degrees.
 The crystall have the same structure as GaPO4.2H2O in 2310449.cif of Mooney-Slater_ACCRA9_1966_1095.cif
 and is somewhat less dense than variscite and metavariscite.
 The structure was refined with TOPAS software.
