摘要：

Two materials, AlPO4-15 and CoAPO-15, with the same aluminophosphate lattice have been obtained by hydrothermal synthesis in the presence of hexamethylenetetramine (HMTA). Their formation is attributed to the influence of species that arise through the decomposition of HMTA, the latter process taking place under synthetic conditions. The Co2+ ion in CoAPO-15 occupies tetragonally deformed octahedral sites, and this causes a slight expansion of the unit cell of CoAPO-15 in comparison to that of AlPO4-15. The Co2+ ion is coordinated not only by the O atoms of the system but also by NH3 molecules. © 1990.
