N2 - Three divalent-metal-containing open-framework aluminophosphates, designated M(II)-CJ50, (|C6H17N2O2| [MAl3P4O16], M=Mg, Mn and Fe), have been hydrothermally synthesized using 2, 2'-(ethylenedioxy)bis(ethylamine) as the organic template. Single crystal and powder X-ray diffraction analyses show that their structures are similar to those of trivalent-metal-containing aluminophosphates M(III)-CJ50 synthesized by using imidazole as template. The differences between M(II)-CJ50 and M(III)-CJ50 are: hetero-metal atoms in M(II)-CJ50 have lower oxidation states owing to the usage of ether amine; in M(II)-CJ50, hetero-metal atoms are coordinated to the two O atoms in each ether amine molecule, whereas in M(III)-CJ50 hetero-metal atoms are coordinated to pairs of imidazole molecules through single N atoms. Moreover, magnetic measurements reveal that the hetero-metal atoms in M(II)-CJ50 are high-spin whereas those in M(III)-CJ50 are low-spin owing to the differences in ligand molecules and oxidation states of hetero-metal atoms.
