N,N′-Bis[(E)-(3-methyl-2-thienyl)methylidene]ethane-1,2-diamine
Two independent half-mol-ecules, each being completed by inversion symmetry, comprise the asymmetric unit of the title compound, C(14)H(16)N(2)S(2). The major difference between the mol-ecules is found in the central C-C bond [the C-N-C-C torsion angles are 114.66 (18) and 128.94 (18)° in the two mol-ecules]. The thio-phene and imine groups are almost co-planar in each case [S-C-C-N torsion ang...

In the title compound, C(11)H(15)ClN(4)O(2), the amino group is involved in intra- and inter-molecular N-H⋯O hydrogen bonds. The former contributes to the mol-ecular conformation, while the latter link the mol-ecules into centrosymmetric dimers. The crystal structure also exhibits weak inter-molecular C-H⋯O inter-actions.

The asymmetric unit of the title compound, C(8)H(6)N(2)O(2), contains two independent mol-ecules, the aromatic rings of which are oriented at a dihedral angle of 1.68 (3)°. Intra-molecular C-H⋯O hydrogen bonds result in the formation of two non-planar six-membered rings, which adopt envelope and twisted conformations. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds link the mol-e...

In the title compound, C(15)H(15)N(3)OS, the thio-urea group is stabilized by an intra-molecular hydrogen bond between the carbonyl O atom and the thio-amide group. A C-H⋯N intramolecular hydrogen bond is also present. Mol-ecules are linked by inter-molecular N-H⋯O and C-H⋯S hydrogen bonds.

The crystal structure of the title compound, C(11)H(12)O(2), consists of dimers which are formed due to inter-molecular O-H⋯O hydrogen bonding. The dimers are linked to each other by C-H⋯O hydrogen bonds, where C-H belongs to the benzene ring and the O atom is of a carbonyl group of an adjoining mol-ecule. There exist two inter-molecular C-H⋯O hydrogen bonds which form five-membered rings. Ther...
