1-(Biphenyl-4-ylcarbon­yl)-3-(2-chloro-4-nitro­phen­yl)thio­urea

The benzene rings of the biphenyl group in the title compound, C20H14ClN3O3S, are nearly coplanar [maximum deviation = 0.20 (3) Å]. The mean plane of the biphenyl group forms a dihedral angle of 5.24 (7)° with the aromatic ring of the nitro­chloro­benzene group. Intra­molecular N—H⋯Cl, N—H⋯O and C—H⋯S hydrogen bonds stabilize the cis–trans conformation of the mol­ecule. In the crystal, mol­ecules are linked by C—H⋯O and C—H⋯S hydrogen bonds into mutually inter­woven corrugated layers parallel to (10-2)

N-(4-Chloro­butano­yl)-N′-(2,5-dimeth­oxy­phen­yl)thio­urea

The title mol­ecule, C13H17ClN2O3S, shows an anti and syn disposition of the butanoyl and 2,5-dimethoxyphenyl groups with respect to the thione and is stabilized by intra­molecular N—H⋯O and weak C—H⋯S hydrogen bonds. In the crystal, inter­molecular N—H⋯S hydrogen bonds link the mol­ecules into centrosymmetric dimers. The crystal structure is stabilized by weak C—H⋯O and C—H⋯S contacts

N-(2,2-Dimethyl­propano­yl)-N′-(2-meth­oxy­phen­yl)thio­urea

In the title compound, C13H18N2O2S, the carbonyl­thio­urea fragment is nearly planar with an r.m.s. deviation of 0.0096 Å. The dihedral angle between carbonyl­thio­urea group and the benzene ring is 19.16 (16)°. There are two intra­molecular N—H⋯O hydrogen bonds, which lead to two pseudo-six-membered rings. Weak intra­molecular C—H⋯S hydrogen bonding also occurs

N-(4-Chloro­butano­yl)-N′-phenyl­thio­urea

The asymmetric unit of the title compound, C11H13ClN2OS, contains two independent mol­ecules. Both mol­ecules maintain a trans–cis configuration with respect to the position of the carbonyl group and the benzene ring against the thione group across the C—N bonds. The mol­ecules are stabilized by intra­molecular N—H⋯O hydrogen bonds. In the crystal, the mol­ecules are linked by inter­molecular N—H⋯S, N—H⋯O and C—H⋯S hydrogen bonds into chains along the c axis. C—H⋯π inter­actions further stabilize the crystal structure

1-(4-Chloro­butano­yl)-3-(2-chloro­phen­yl)thio­urea

The asymmetric unit of the title compound, C11H12Cl2N2OS, contains two crystallographically independent mol­ecules with different conformations: the benzene ring and the thio­urea fragment form dihedral angles of 74.32 (11) and 89.39 (11)°. One amino group in each mol­ecule is involved in intra­molecular N—H⋯O and inter­molecular N—H⋯O hydrogen bonding: the latter links pairs of independent mol­ecules into dimers. In the crystal, weak N—H⋯S inter­actions link these dimers into chains propagating along the c axis

1-(1,3-Benzothia­zol-2-yl)-3-(4-chloro­benzo­yl)thio­urea

The title compound, C15H10ClN3OS2, adopts a cis–trans configuration across the thio­urea C—N bonds with respect to the positions of the benzothia­zole and 4-chloro­benzoyl groups relative to thiono S atom. An intra­molecular N—H⋯O hydrogen bond is present. In the crystal structure, mol­ecules are linked by a weak inter­molecular N—H⋯S hydrogen bond, forming centrosymmetric dimers

2-(4-Chloro­phen­yl)-1-phenyl-1H-benz­imidazole

In the title compound, C19H13ClN2, the dihedral angle formed by the imidazole core with the chloro­phenyl and phenyl rings are 24.07 (4) and 67.24 (4)°, respectively

1-(Biphenyl-4-ylcarbon­yl)-3-(4-nitro­phen­yl)thio­urea

In the title compound, C20H15N3O3S, the two benzene rings of the biphenyl group form a dihedral angle of 40.11 (15)°. The conformation of the mol­ecule is trans–cis and is stabilized by two intra­molecular N—H⋯O and C—H⋯S hydrogen bonds. In the crystal structure, the mol­ecules are linked by weak π–π stacking inter­actions [centroid–centroid distance = 3.991 (2) Å]

N-(4-Chloro­butanoyl)-N′-(2-fluoro­phen­yl)thio­urea

In the title compound, C11H12ClFN2OS, the asymmetric unit consists of two indenpendent mol­ecules. Both mol­ecules maintain a trans–cis configuration of the positions of the butanoyl and fluoro­phenyl groups with respect to the thiono group across their C—N bonds and are stabilized by classical intra­molecular N—H⋯O hydrogen bonds. In the crystal, inter­molecular N—H⋯O, C—H⋯S and N—H⋯S hydrogen bonds link the mol­ecules into infinite chains along the c axis

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

In the title compound, C12H15N3O3S, there is an intra­molecular N—H⋯O hydrogen bond. The crystal structure is stabilized by inter­molecular N—H⋯O, N—H⋯S and C—H⋯S hydrogen bonds, forming a two-dimensional network parallel to the ac plane
