The title compound, C(11)H(9)N(3)O(2)S, crystallizes with two independent mol-ecules in the asymmetric unit. The central thio-urea core makes dihedral angles of -3.3 (3) and 0.6 (3)° with the furan carbonyl groups in each mol-ecule, whereas the pyridine ring is inclined by 4.63 (2) and 11.28 (7)°, respectively. The trans-cis geometry of the thio-urea fragment is stabilized by an intra-molecular...

In the title mol-ecule, C(13)H(13)N(3)O(6)S(2), the two benzene rings form a dihedral angle of 28.59 (7)°. The crystal sructure exhibits weak inter-molecular N-H⋯O, C-H⋯O and C-H⋯N hydrogen bonds and π-π inter-actions [centroid-to-centroid distance = 3.899 (3) Å].

In the title compound, C(17)H(17)ClN(2)O(2), the asymmetric unit contains half a mol-ecule with a centre of symmetry at the mid-point of the central C-C bond. The conformations of the amide O atoms are anti to the methyl-ene atoms. Further, the N-H bonds in the amide fragments are anti to the ortho-chloro/methyl groups in the adjacent benzene rings. The dihedral angle between the benzene ring a...

The title compound, C(18)H(21)BrN(2)O, crystallizes with two mol-ecules (A and B) in the asymmetric unit (Z' = 2). The major differences between the two mol-ecules are related to the conformations adopted by their n-butyl side chains. The phenyl rings in both mol-ecules are almost perpendicular, making dihedral angles of 79.2 (3) and 80.8 (3)°. The amide units are planar (r.m.s. deviations of 0...
