N2 - The reaction of sodium N-morpholine acetate with selenic and sulfuric acid and uranyl nitrate results in the formation of two novel open-framework compounds, |Na(Hmfa)|[(UO 2) 2(SeO 4) 3(H 2O)](H 2O) 2 (NaUSe) and [Na 2(SO 3OH)(Hmfa)]|(UO 2)(SO 4) 2| (NaUS), respectively. Despite identical synthetic procedures, sulfate structure dramatically differs from selenate compound. Their common feature is an open-framework featuring two-dimensional system of channels occupied by protonated morpholino-N-acetic acid species. Coordination of Na atoms is different. In NaUSe, [(UO 2) 2 (SeO 4) 3(H 2O)] 2- layers are pillared by {Na 2O 8(H 2O) 2(Hmfa) 2} complexes to form a microporous framework. In NaUS, UO 7 and SO 4 polyhedra of [(UO 2)(SO 4) 2] 2- chains share common oxygen atoms with Na-centered tetrameric complexes providing a three-dimensional integrity of the structure. Both of the compounds are characterized by IR spectroscopy.
