چکیده
The title compound, C(9)H(11)N(2)O(5) (+)·Cl(-)·H(2)O, was synthesized from (1S,2S)-2-amino-1-(4-nitro-phen-yl)propane-1,3-diol in four steps. As demonstrated by this work, no racemization occurs during this synthetic procedure. The crystal structure displays many inter-molecular hydrogen bonds between the acidic cation, chloride anions and the water mol-ecules, forming a three-dimensional network. An intra-molecular bond between the ammonium group and a hydroxyl O atom is also present.

The structure of the title compound, C(15)H(21)N(3)O(6)·H(2)O, is of inter-est with respect to assumed anti-cancer activity. The title mol-ecules are linked through inter-molecular O-H⋯O hydrogen-bonded chains along the a axis. These chains are connected by inter-molecular N-H⋯O hydrogen bonds through the crystallographic screw axis along [010], forming layers, which are stabilized by other N-H...
