In the title compound, the planes of the phen­yl and 2-(1-imino­eth­yl)phenol fragments form dihedral angles of 28.18 (11) and 28.51 (11)°, respectively, with the central –N—C(=O)– fragment. The mol­ecule is stabilized by inter­molecular N—H...O hydrogen bonds, which form a one-dimensional chain parallel to the a axis.

The 4-methoxy­benzoyl and 3-(hydroxy­methyl)­phenyl groups in the title compound, C16H16N2O3S, are trans and cis, respectively, with respect to the thione group across the C—N bonds. The central carbonyl­thio­urea moiety makes dihedral angles with the 4-methoxy­benzoyl and 3-(hydroxy­methyl)­phenyl fragments of 33.48 (7) and 45.96 (6)°, respectively. The mol­ecules are stabilized by intermolecular N—H...O and O—H...S hydrogen bonds to form tetramers.

The title compound, C19H18O5, is a diastereoisomer of crotocaudin, both being isolated from the plants of genus Croton. In isocrotocaudin, the furan moiety makes a dihedral angle with the adjacent lactone of 13.53 (17)°. The cyclo­hexyl ring of the diterpene moiety adopts a chair confirmation. The weak intermolecular C—H...O hydrogen bonds link the mol­ecules into linear chains along the c axis.

The title compound, [Fe2(C17H16N2O2)3], was isolated from the reaction between iron(III) perchlorate hydrate and a mixture of 1,3-bis­(salicylideneamino)propane and triethyl­amine in ethanol. Recrystallization from a dichloro­ethane solution resulted in a porous solvent-free array of mol­ecules. The molecule lies on a special position with twofold symmetry.

The title compound, (2S)-2-(3-benzoyl­thio­ureido)-3-(1H-imidazolium-4-yl)­propionate, C14H14N4O3S, is zwitterionic with protonated positively charged imidazoyl and deproton­ated negatively charged carboxyl­ate groups. The intermolec­ular hydrogen bonds, C—H...O and N—H...O, involve all the O atoms with the H atoms from the amine and imidazoyl­ium, forming a two-dimensional network parallel to the (100) plane.

The 3-methyl­butyric acid and benzo­yl fragments in the title compound, C13H16N2O3S, are cis and trans, respectively, with respect to the thiono group across the thio­urea C—N bonds. In the crystal structure the mol­ecules are stabilized by inter­molecular N—H...O, O—H...S and C—H...O hydrogen bonds to form zigzag chains parallel to the b axis.

In the title compound, C10H10N2O3S·C2H6SO, the ethanoic acid fragment and benzene ring make dihedral angles of 3.61 (9) and 20.77 (9)°, respectively, with the central thio­urea N2CS group. In the crystal structure, an inter­molecular O—H...O hydrogen bond exists between the hydr­oxy group of the ethanoic acid fragment and the O atom of the dimeth­yl sulfoxide solvent mol­ecule.

In the title compound, C18H18N2O4S·CH4O, the 4-methoxy­phenyl and benzyl groups make dihedral angles of 7.28 (18) and 57.54 (18)°, respectively, with the central carbonyl­thio­urea group. The crystal structure is stabilized by inter­molecular hydrogen bonds, N—H...O, O—H...O and C—H...O, forming a two-dimensional network parallel to the bc face.
