(a) The crystal structure of [NaFe(C2O4)2(H2O)4]n, (I), viewed along the c axis and showing the role of the hydrogen-bond system (dashed lines) in the structure stabilization. The hydrogen bonds connect adjacent rows running in the same direction, as well as the nearest rows with perpendicular [100] and [010] directions. (b) Details of the hydrogen-bond geometry.
