چکیده
The title mol-ecule, C(24)H(29)N(3)O(6), has a nearly planar ten-atom C(3)N(3)O(4) core, on account of both N-H groups forming six-membered-ring intra-molecular hydrogen bonds to carbamate carbonyl O atoms. The absolute configuration was determined from resonant scattering of light atoms in Mo Kα radiation, agreeing with the configuration of starting materials.

In the chiral title compound, C(15)H(22)N(4)O(2)S(2), there are two mol-ecules in the asymmetric unit with distinctly different conformations, as quanti-fied by torsion angles. The dihedral angles between the thio-imidazole rings are 81.59 (5) and 67.04 (4)°. One mol-ecule exhibits local twofold rotation symmetry, while the other displays no local symmetry. Inter-molecular C-H⋯O and C-H⋯S inter...

In the title compound, 2C12H20N2 (2+)·2H3O(+)·P6O18 (6-)·2H2O, a protonated water mol-ecule bridges the centrosymmetrical anionic P6O18 ring via O-H⋯O hydrogen bonds. The centrosymmetric hydrogen-bonded rings formed by four oxonium cations and four phosphate anions can be described by an R 4 (8)(36) graph-set motif. The ring motifs are connected by hydrogen bonds into inorganic layers perpendic...
