20-O-β-d-Xylopyranosyl(1→6)-β-d-glucopyranosyl-20(S)-protopanaxadiol methanol solvate
The title compound, C(41)H(70)O(12)·CH(4)O, was prepared by microbial transformation. Within the steroid skeleton of the mol-ecule, three six-membered rings exhibit a chair conformation, while the five -membered ring adopts an envelope conformation. The two pyranosyl rings also adopt chair conformations. The mol-ecules are held together by an extensive O-H⋯O hydrogen-bonding network.
متن کاملN′-[1-(2-Hydroxyphenyl)ethylidene]-2-nitrobenzohydrazide methanol solvate
In the title compound, C(15)H(13)N(3)O(4)·CH(3)OH, the dihedral angle between the two substituted benzene rings is 66.7 (2)°. An intra-molecular O-H⋯N hydrogen bond is observed in the Schiff base mol-ecule. In the crystal structure, the Schiff base and solvent mol-ecules are linked into chains running along the a axis by inter-molecular O-H⋯O and N-H⋯O hydrogen bonds.

In the title compound, C(27)H(27)N(3)O(3)S(3)·CH(4)O, the dihedral angles formed by the mesitylene ring with the three oxopyridyl rings are 89.6 (1), 75.5 (1) and 80.69 (1)°, indicating that all three are nearly perpendicular to the mesitylene ring. Intra-molecular C-H⋯S hydrogen bonds generate S(6) ring motifs. The crystal structure is stabilized by intra-molecular C-H⋯S and inter-molecular C-...

In the title organic salt, C(18)H(14)N(3)O(+)·ClO(4) (-)·CH(4)O, there is a π-π stacking inter-action between neighbouring 1,10-phenanthroline rings and the relevant distances are 3.5453 (18) Å for the centroid-centroid distance and 3.354 Å for the perpendicular distance. There is also a relatively close contact between a C-H bond and a symmetry-related pyridine ring. There are classical N-H⋯O ...
متن کامل[(E)-(1-Phenylethylidene)amino]urea methanol monosolvate
In the title compound, C(9)H(11)N(3)O·CH(4)O, the semicarbazone moiety is nearly planar [maximum deviation = 0.017 (2) Å] and is twisted by a dihedral angle of 29.40 (13)° with respect to the phenyl ring. The semicarbazone moiety and phenyl ring are located on opposite sides of the C=N bond, showing the E configuration. An inter-molecular O-H⋯O and N-H⋯O hydrogen-bonding network occurs in the c...
