(S)-2-Ammonio-3-(4-nitrophenyl)propanoate monohydrate
The title compound, C(9)H(10)N(2)O(4)·H(2)O, exists as a zwitterion with a deprotonated carboxyl group and a protonated amino group. The crystal packing is stabilized by N-H⋯O and O-H⋯O hydrogen bonds, building sheets parallel to the (001) plane. The absolute configuration was deduced from the synthetic pathway.

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...

The title compound, C(7)H(7)NO(3)·H(2)O, which crystallized as a hydrate, was obtained from an extraction of the plant species Saussurea atkinsonii of the asteraceae family collected from the hilly area (Ayubia) of Pakistan during the flowering season. The dihedral angle between the benzene ring and the carboxyl-ate group is 25.64 (5)°. In the crystal, the packing is consolidated by N-H⋯O and O...

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 netw...
