چکیده
The mol-ecule of the title ethanol solvate, C(15)H(21)N(3)O(6)·C(2)H(6)O, adopts a curved shape; the conformation about the imine bond [N=N = 1.287 (3) Å] is E. The amide residues occupy positions almost orthogonal to each other [dihedral angle = 85.7 (2)°]. In the crystal, a network of O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds leads to the formation of supra-molecular arrays in the ab plane with the ethanol mol-ecules lying to the periphery on either side. Disorder in the solvent ethanol mol-ecule was evident with two positions being resolved for the C atoms [site occupancy of the major component = 0.612 (10)].

The organic mol-ecule in the title dihydrate, C(18)H(19)N(3)O(6)·2H(2)O, adopts a twisted U-shape with the major twists evident about the chiral C atom [the C-N-C-C torsion angle is -88.2 (4) °] and about the oxygen-benzyl bond [C-O-C-C = 74.2 (4) °]. The conformation about the imine bond [1.290 (4) Å] is E and an intra-molecular O-H⋯N hydrogen bond helps to establish the near coplanarity of th...

The relative stereochemistry of the title compound, C(20)H(23)NO(3), was established by X-ray analysis. The asymmetric unit contains two independent mol-ecules. In the crystal structure, each type of mol-ecule forms a centrosymmetric dimer via pairs of inter-molecular O-H⋯O hydrogen bonds, resulting in an R(2) (2)(10) loop in each case.

The crystal structures of tert-butyl (5-chloro-penta-2,4-diyn-1-yl)carbamate, C10H12ClNO2 (II), and tert-butyl (5-iodo-penta-2,4-diyn-1-yl)carbamate, C10H12INO2 (IV), are isomorphous to previously reported structures and accordingly their mol-ecular and supra-molecular structures are similar. In the crystals of (II) and (IV), mol-ecules are linked into very similar two-dimensional wall organiza...
