tert-Butyl N-[(S)-1-hydrazinecarbonyl-2-hydroxy­ethyl]carbamate

In the title compound, C(8)H(17)N(3)O(4), the dihedral angle between the hydrazinecarbonyl and carbamate groups is 44.94 (12)°, and the carbonyl groups are anti to each other. In the crystal, the hydr­oxy group forms an O—H⋯N(a) (a = amine) hydrogen bond and each of the four N—H atoms forms an N—H⋯O hydrogen bond; the hydrazinecarbonyl O atom accepts two such bonds. This results in two-dimensional arrays in the ab plane, mediated by the hydrogen bonding, sandwiched by tert-butyl groups.
