A low-resolution X-ray molecular structure of the title hydrated salt, [Na(C19H21N6O6)]·2H2O, displays scorpionate character and resolves apparent ambiguities between solution and solid-state NMR spectroscopies. The13C NMR CPMAS spectrum is consistent with this structure showing some splittings, which have been rationalized using GIAO/B3LYP/6-311++G(d,p) theoretical calculations.
