An important application of melamine phosphates is in the development of environmentally friendly flame retardant polymeric materials. We used proton spectroscopy under magic-angle-spinning conditions to gain insight into the proton proximities and molecular structure of melamine phosphates. Experimental results are presented and discussed. The results were obtained by applying homonuclear decoupling sequences to record high-resolution proton and heteronuclear correlation spectra of types 1H–13C, 1H–15N and 1H–31P. Our goal is to determine the proton positions and hydrogen bonds in the melamine phosphates, which may be of significance for the function of these compounds as flame retardants.
