Investigating Polyphosphates with 31P NMR Spectroscopy

Abstract The experiment investigated the use of 31P NMR spectroscopy to determine the structure of polyphosphate anions. The structures of two cyclic (P4O124- and P3O93-) and two linear (P3O105- and P2O74-) were found. Introduction Phosphorus (V) has many polyphosphate oxo-anions which usually existing as either linear or cyclic phosphates. It is known that the linear phosphates are of the form [PnO3n+1](n+2)- and the cyclic phosphates in the form [PnO3n]n- (1). Two of these were synthesised: P3O105- and P4O124- using the […]
