Abstract
Two new porous gallophosphates were synthesized in aqueous medium using N,N,N',N'-tetramethylethylenediamine as organic template. The material obtained in the presence of fluoride anions corresponds to the fluorogallophosphate ULM-18 whereas, the other gallophosphate synthesized in the absence of F- displays a new three-dimensional framework containing four-, five- and six-coordinated gallium atoms. The two materials were characterized by several techniques such as SEM, elemental analysis, powder X-ray diffraction and solid state NMR spectroscopy.
