Abstract

Nickel (II)-substituted aluminophosphates of structure types 21 and 12 (NiAPO-21 and NiAPO-12) have been prepared hydrothermally in the presence of ethylenediamine as the template. U.v.-visible spectroscopy of NiAPO-21 suggests that Ni(II) replaces hexacoordinated aluminum of the AlPO4-21 framework and is octahedrally coordinated by the O atoms of the aluminophosphate skeleton and also by H2O and en molecules. It has also been found that in the presence of copper(II) no aluminophosphate-type products can be obtained. © 1991 Butterworth-Heinemann.
