Propyl 2-(3-benzoyl-thio-ureido)acetate.

The title compound, C13H16N2O3S, is a thiourea derivative with benzoyl and propoxycarbonylmethyl groups attached to the two terminal N atoms. These groups adopt trans and cis configurations, respectively, with respect to the S atom across the thiourea C—N bonds. The compound crystallizes in the P21/c space group with Z = 8, resulting in two unique molecules in the asymmetric unit linked by C—H⋯S and C—H⋯O hydrogen bonds, forming a one-dimensional zigzag chain along the c axis.

Butyl 2-(3-benzoyl­thio­ureido)acetate

The title compound, C12H14N2O3S, adopts a cis–trans geometry of the thiourea group and is stabilized by intramolecular hydrogen bonds between the carbonyl O atoms and the H atom of the thioamide group and by a C—H⋯S interaction. Molecules are linked by two intermolecular hydrogen bonds (C—H⋯O and N—H⋯O), forming a one-dimensional chain parallel to the c axis.

Methyl 2-(3-benzoylthioureido)acetate

In the title compound, C11H12N2O3S, the methyl acetate and benzoyl groups adopt a cis-trans configuration with respect to the thiono S atom across the C—N bonds. An intramolecular N—H⋯O hydrogen bond is observed. In the crystal packing, molecules are linked by intermolecular N—H⋯S and C—H⋯O hydrogen bonds to form a two-dimensional network lying parallel to (101).

3-(3-Meth-oxy-benzo-yl)-1,1-diphenyl-thio-urea.

The thiono and carbonyl groups in the title compound, C21H18N2O2S, adopt an anti disposition with respect to the central C—N bond. The diphenylamine rings are twisted relative to each other by a dihedral angle of 82.55 (10)°. The 3-methoxybenzoyl fragment is twisted relative to one of the diphenylamine rings, forming a dihedral angle of 74.04 (9)°. In the crystal, pairs of intermolecular N—H⋯S hydrogen bonds link the molecules into centrosymmetric dimers, forming columns parallel to the a axis.

2-Bromo-N-(dibenzyl-carbamothioyl)benzamide.

The 2-bromobenzoyl group in the title compound, C22H19BrN2OS, adopts an E conformation with respect to the thiono S atom across the N—C bond. In the crystal structure, the molecule is stablized by N—H⋯O intermolecular hydrogen bonds, forming a one-dimensional chain along the b axis.

Cinnamoyl­thio­urea

In the title compound [systematic name: 1-(3-phenylprop-2-enoyl)thiourea], C10H10N2OS, the acetylthiourea fragment and the phenyl ring adopt an E configuration. The roughly planar but-2-enoylthiourea fragment [maximum deviation = 0.053 (3) Å] forms a dihedral of 10.54 (11)° with the phenyl ring. An intramolecular N—H⋯O hydrogen bond generates an S(6) ring. In the crystal, molecules are linked into sheets parallel to (100) by N—H⋯S hydrogen bonds.

1,1-Dibenzyl-3-(3-chloro­benzo­yl)thio­urea

In the title compound, C22H19ClN2OS, the thiono and carbonyl groups are trans positioned with respect to a partially double C—N bond. The amide group is twisted relative to the thiourea fragment, forming a dihedral angle of 46.75 (11)°. In the crystal, intermolecular N—H⋯S and C—H⋯O hydrogen bonds link the molecules into a one-dimensional polymeric structure parallel to the c axis.

(E)-Methyl 2-(3-cinnamoyl­thio­ureido)acetate

In the title compound, C13H14N2O3S, the methyl 2-(3-formylthioureido)acetate fragment and the phenyl ring adopt an E configuration. The molecule exhibits an intramolecular N—H⋯O hydrogen bond, which completes a six-membered ring. The crystal packing is stabilized by intermolecular N—H⋯S contacts, generating a two-dimensional hydrogen-bonding network.

Methyl 3-(3-benzoyl­thio­ureido)propano­ate

In the title compound, C12H14N2O3S, the propyl acetate group and the benzoyl group adopt a cis–trans conformation, respectively, with respect to the thiono S atom across the C—N bonds. The phenyl ring is twisted relative to the the thiourea mean plane, forming a dihedral angle of 24.16 (9)°. An intramolecular N—H⋯O hydrogen bond occurs. The crystal packing is stabilized by intermolecular N—H⋯O and C—H⋯O hydrogen bonds, forming a chain along the a axis.
