Abstract:

Open-framework metal-substituted aluminophosphates have attracted more attentions owing to their interesting structural chemistry and potential applications in catalysis, ion exchange, magnetism, and photoluminescence. A series of metal-substituted aluminophosphates MAl(PO4)2[(C2H5)2NH2](denoted as MAPO-CHA, M=Mn, Fe, Co, Zn) was prepared under the hydrothermal conditions. Their frameworks are analogous to zeotype CHA structure in which 50% of the aluminum sites are replaced by transitional-metal ions. These compounds show photoluminescent properties, but the emission intensities are different due to the different transitional metals. Magnetic measurements reveal that there is very weak antiferromagnetic interaction among the metal centers of MAPO-CHA(M=Mn, Fe, Co). Crystal data of MnAPO-CHA: space group R3, a=1.4003(2) nm, c=1.5236(3) nm, V=2.5873(7) nm3, Z=9.
