Abstract

The title compound, NaFe[(O3PCH(OH)CO2)] or {Na[Fe(C2H2O6P)]}n, was synthesized under mild hydrothermal conditions. The FeII ion is octahedrally coordinated; all O atoms from the 2‐hydroxyphosphonoacetate(3−) are involved in metal coordination. The overall structure can be described as a three‐dimensional open framework with channels running along the a axis and with the charge?compensating Na+ cations located inside these channels. This architecture is further stabilized by a number of O—H...O hydrogen bonds involving the protonated hydroxyl O atoms and carboxylate O atoms.
