Fig. 1. 31P NMR spectra of the hydrolysis of DMNP (1) [4.2 mM] to nitrophenol (NP) and dimethyl phosphate (DMP) (2) with {Y3(HPO3)Sb3W28} [2.5 mM] in Tris–HCl [125 mM] at pD 7.0 25 °C. The virtually unchanged singlet peak at 2.81 ppm corresponds to the {HPO3} group (3) incorporated in the diamagnetic representative {Y3(HPO3)Sb3W28} suggesting solution stability of the isostructural series under turnover conditions.
