Supporting information
Dihydroxyacetone (0.90 g, 10 mmol) and hydrazine hydrate (0.49 ml, 10 mmol) in ethanol (50 ml) were heated for 12 h. Slow evaporation of the solvent gave colourless crystals in 80% yield. The formulation of the organic molecule was established by 1H and 13C NMR as well as by mass spectroscopies.
The amino and water H-atoms were located in a difference Fourier map, and were refined with a distance restraint of N-H = O-H = 0.85 (1) Å; their Uiso parameters were freely refined. Carbon-bound H-atoms were placed in calculated positions (C-H = 0.97 Å) and were included in the refinement in the riding model approximation, with Uiso(H) set to 1.2Ueq(C). The highest peak and the deepest hole are located 0.73 and 0.58 Å from O1W. Although the displacement parameters of atom O1W are relatively large, no disorder is expected as its H-atoms could be located and refined.
