    IN THE TITLE COMPOUND [SYSTEMATIC NAME: 1-(3-phenyl-prop-2-eno-yl)thio-urea], C(10)H(10)N(2)OS, the acetyl-thio-urea fragment and the phenyl ring adopt an E configuration. The roughly planar but-2-enoyl-thio-urea fragment [maximum deviation = 0.053 (3) Å] forms a dihedral of 10.54 (11)° with the phenyl ring. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring. In the crystal, mol-ecules are linked into sheets parallel to (100) by N-H⋯S hydrogen bonds.

    In the title compound, C(14)H(16)N(2)O(3)S, the phenyl ring and the ethyl 2-(3-formyl-thio-ureido)acetate fragment adopt an E configuration with respect to the C=C bond. An intra-molecular N-H⋯O hydrogen bond generating an S(6) ring motif is observed. In the crystal, mol-ecules are linked by N-H⋯S, C-H⋯S and C-H⋯O hydrogen bonds, forming sheets lying parallel to the ab plane.

    PMID: 21588609 DOI: 10.1107/S1600536810030084
    In the title compound, C(13)H(14)N(2)O(3)S, the methyl 2-(3-formyl-thio-ureido)acetate fragment and the phenyl ring adopt an E configuration. The mol-ecule exhibits an intra-molecular N-H⋯O hydrogen bond, which completes a six-membered ring. The crystal packing is stabilized by inter-molecular N-H⋯S contacts, generating a two-dimensional hydrogen-bonding network.

    In the title compound, C(11)H(12)N(2)O(3)S, the methyl acetate and benzoyl groups adopt a cis-trans configuration with respect to the thiono S atom across the C-N bonds. An intra-molecular N-H⋯O hydrogen bond is observed. In the crystal packing, mol-ecules are linked by inter-molecular N-H⋯S and C-H⋯O hydrogen bonds to form a two-dimensional network lying parallel to (101).

    PMID: 21581027 DOI: 10.1107/S1600536808033540
    In the title compound, C(14)H(18)N(2)O(3)S, the butyl acetate fragment and the benzoyl group adopt a cis-trans configuration, respectively, with respect to the thiono S atom across the C-N bonds. In the crystal packing, the mol-ecules are linked by inter-molecular N-H⋯O and C-H⋯O hydrogen bonds to form a one-dimensional chain along the c axis. The terminal butyl C atom is disordered with occupancies 0.82 (2)and 0.18 (2).

    PMID: 21580948 DOI: 10.1107/S1600536808030596
    The title compound, C(13)H(16)N(2)O(3)S, is a thio-urea derivative with benzoyl and propoxycarbonyl-methyl groups attached to the two terminal N atoms. These groups adopt trans and cis configurations, respectively, with respect to the S atom across the thio-urea C-N bonds. The compound crystallizes in the P2(1)/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.

    PMID: 21201710 DOI: 10.1107/S1600536808024896
    The title compound, C(12)H(14)N(2)O(3)S, adopts a cis-trans geometry of the thio-urea group and is stabilized by intra-molecular hydrogen bonds between the carbonyl O atoms and the H atom of the thio-amide group and by a C-H⋯S interaction. Mol-ecules are linked by two inter-molecular hydrogen bonds (C-H⋯O and N-H⋯O), forming a one-dimensional chain parallel to the c axis.

    PMID: 21579744 DOI: 10.1107/S1600536809055834
    The mol-ecule of the title compound, C(22)H(18)N(4)O(2)S(2), lies across a crystallographic inversion centre. The central benzene ring forms dihedral angles of 29.39 (9) and 79.11 (12)°, respectively, with the thio-urea unit and the terminal phenyl ring. Intra-molecular N-H⋯O hydrogen bonds generate two S(6) ring motifs. In the crystal, mol-ecules are linked into chains along [10] by inter-molecular N-H⋯S hydrogen bonds.
