摘 要:An open-framework gallophosphate, Ga_9(PO_4)_ 12[(H_3TREN)(H_2TREN)_3]·xH_2O was hydrothermally synthesized at 453 K with tris(2-aminoethyl) amine(TREN) as the organic template and characterized by single-crystal X-ray diffraction. Ga_9(PO_4)_ 12[(H_3TREN)(H_2TREN)_3]·xH_2O crystallized in a cubic space group I43m, with a=1.68552(3) nm and Z=2. The structure contains 12-membered ring channels and supercages of 1.434 nm in diameter, and is an analogue of Al_9(PO_4)_ 12(C_ 24H_ 91N_ 16)·17H_2O. Template-TREN in the supercage was different from triethylenetetraamine(TETA) used in the initial reaction mixture due to the construction transformation. The TETAs transformed into the TRENs due to the low interaction energy between the template and framework. We verified it via energy calculation and liquid state NMR.An open-framework gallophosphate, Ga_9(PO_4)_ 12[(H_3TREN)(H_2TREN)_3]·xH_2O was hydrothermally synthesized at 453 K with tris(2-aminoethyl) amine(TREN) as the organic template and characterized by single-crystal X-ray diffraction.
