N-(3-Chloro­phen­yl)-N′-(3-methyl­phen­yl)succinamide

The asymmetric unit of the title compound, C(17)H(17)ClN(2)O(2), contains one half-mol-ecule with a center of inversion at the mid-point of the central C-C bond. The amide N-H group is anti to the meta-chloro/methyl groups in the adjacent benzene rings. The dihedral angle between the benzene ring and the NH-C(O)-CH(2) segment is 43.5 (1)°. In the crystal, inter-molecular N-H⋯O hydrogen bonds li...

N-(3-Nitro­phen­yl)-N′-pivaloylthio­urea

In the title compound, C(12)H(15)N(3)O(3)S, there is an intra-molecular N-H⋯O hydrogen bond. The crystal structure is stabilized by inter-molecular N-H⋯O, N-H⋯S and C-H⋯S hydrogen bonds, forming a two-dimensional network parallel to the ac plane.

N-(3-Chloro­propion­yl)-N′-phenyl­thio­urea

The title compound, C(10)H(11)ClN(2)OS, adopts a cis-trans configuration with respect to the position of the phenyl and 3-chloro-propionyl groups relative to the thiono group across the C-N bonds. The benzene ring is perpendicular to the propionyl thio-urea fragment with a dihedral angle of 82.62 (10)°. An intra-molecular N-H⋯O inter-action occurs. The crystal structure is stabilized by inter-m...

N-(3-Chloro­benzo­yl)-3-nitro­benzene­sulfonamide

In the title compound, C(13)H(9)ClN(2)O(5)S, the dihedral angle between the two benzene rings is 83.5 (1)°. In the crystal, mol-ecules are linked via N-H⋯O(S) hydrogen bonds into helical chains running along the b axis.
