An ionic 2D inorganic–organic hybrid of tris[((1H-tetrazol-5-yl)methyl) morpholine] dodecatungstophosphate(V) pentahydrate: Synthesis X-ray crystal structure and spectroscopic characterizations

A unique ionic hybrid material [C6H12N5O]3[(PO4)W12O36]·5H2O has been synthesized from the reaction of ((1H-tetrazole-5-yl)methyl)morpholine and α-H3[(PO4)W12O36]·21H2O. It has successfully been characterized by elemental analysis, IR and 1H NMR spectroscopies, TGA and single-crystal X-ray diffraction method. The title compound is constructed from the three [C6H12N5O]+ cations and α-Keggin [(PO4)W12O36]3− polyoxoanion. The most remarkable structural feature of this hybrid can be described as two-dimensional inorganic infinite plane-like (2D/∞[(PO4)W12O36]3−) which forming via van der Waals interactions along the x axis.
