One way to obtain new materials is to exploit the in situ generation of the structure-directing agent. By this synthetic route, solvents or precursors of the templates are introduced into the starting mixtures, and during the synthesis, they partly decompose into molecules that act as templates. This paper deals with the synthesis of a fluorogallophosphate with a new template precursor, the N-formylmorpholine. This compound, used as main solvent, is unstable in acidic media. At high temperature it decomposes and generates in situ the morpholine molecules. We report the structure of a two-dimensional fluorogallophosphate named Mu-38 structurally related to ULM-9. This compound Ga3P3O12F3[C4H10NO]3 (Z = 4) consists of anionic inorganic layers containing single four rings units linked and charge-balanced by protonated morpholine. It was also characterized by powder XRD, SEM, elemental and thermal analyses, and solid state NMR spectroscopy (13C, 19F and 31P MAS and 31P CP MAS experiments).
