Abstract:	Abstract The fully deprotonated anion of 1,3,5-benzene-triphosphonic acid 1,3,5-C₆H₃PO₃^2?]₃ gives rise to deceptively simple ¹H and ³¹P NMR spectra due to a corresponding AX]₃ spin system. The ¹³C{¹H} NMR spectrum reveals two ¹³C isotopomers which are identified via AXX′₂ systems. Results from analysis and iteration are described.
