摘要

One pot synthetic aluminosilicale and gallosilicate sodalites containing acetate guest anion have been synthesized successfully under hydrothermal conditions at 100℃. This paper deals with the comparison of X-ray powder data with single crystal data for Na_8[AlSiO_4]_6(CH_3COO)_2 and the characterization of a new Na_8[GaSiO_4]_6(CH_3COO)_2 sodalite. The products obtained were characterized by IR, X-ray powder diffraction, MAS NMR, SEM and thcrmogravimetry technique. Crystal structures were refined in the space group P43n from X-ray powder data using the Rietvcld refinement method with the unit cell parameter a = 9.0679 A, for aluminosilicate and a = 9.2119 A, for gallosilicate sodalite. The aluminosilicate and gallosilicate framework shows regular bonding with bond angles of Al-O-Si = 146.241°, Ga-O-Si = 141.294°. ~(29)Si MAS NMR chemical shift values verify Al/Si and Ga/Si ordering of the framework constituents.
