In the title 1/2 adduct, C(10)H(8)N(2)·2C(7)H(6)O(2)S, the dihedral angle between the pyridine rings is 18.41 (11)°. In the thio-phene-acrylic acid mol-ecules, the dihedral angles between the respective thio-phene and acrylic acid units are 5.52 (17)° and 23.92 (9)°. In the crystal, the components are linked via O-H⋯N hydrogen-bonding inter-actions, forming units of two 3-thio-phene-acrylic aci...

In the title compound, C(19)H(14)OS, the naphtho-thio-phene moiety is almost planar except for the S atom of the five-membered ring, which is situated 0.047 (6) Å out of the C(4) plane (with an r.m.s. deviation of fitted atoms = 0.0009 Å). The dihedral angle between the naphtho-thio-phene plane and the attached meth-oxy-phenyl ring is 67.6 (2)°. In the crystal, a C-H⋯π inter-action is observed ...

The title chiral imine, C(17)H(15)NS, has been obtained via a direct synthesis route. The imine group displays the common E configuration, and is almost coplanar with the thio-phene heterocycle; the dihedral angle between the C=N-C group and the thio-phene ring is 5.1 (8)°. In contrast, the naphthyl group makes an angle of 83.79 (13)° with the thio-phene ring. The observed solid-state mol-ecula...

The asymmetric unit of the title compound, C(18)H(11)NO(2)S, contains two crystallographically independent mol-ecules. In one mol-ecule, the oxazole and thio-phene rings are oriented at dihedral angles of 17.40 (9) and 18.18 (7)° with respect to the naphthalene ring system, while the oxazole and thio-phene rings are oriented to each other at a dihedral angle of 0.86 (9)°. In the other mol-ecule...

In the crystal structure of the polymeric title compound, [Mn(NCS)2(C10H8N2)] n , the Mn(II) cations are coordinated by one chelating 2,2'-bi-pyridine ligand and four thio-cyanate anions (two N- and two S-coordinating), forming a distorted [MnN4S2] octa-hedron. The asymmetric unit consists of one manganese cation located on a twofold rotation axis and half of a 2,2'-bi-pyridine ligand, the othe...

In order to search for new antitumor drugs with high efficiency and low toxicity, a series of novel 4-aminoquinazoline derivatives containing 1,3,4-thiadiazole group were designed, synthesized evaluated antiproliferative activity against four human cancer cell lines (H1975, PC-3, MCF-7 HGC-27) using MTT assay in vitro. Among them, compound N-(5-((3,5-dichlorobenzyl)thio)-1,3,4-thiadiazol-2-yl)-...

The title compound, C(15)H(11)N(3)OS(2), was synthesized from benzoyl thio-cyanate and 2-amino-benzothia-zole in dry acetone. The thio-urea group is in the thio-amide form. The mol-ecules are stabilized by two inter-molecular C-H⋯S and C-H⋯O hydrogen bonds. Intra-molecular N-H⋯O hydrogen bonding results in a pseudo-S(6) planar ring with dihedral angles of 11.23 and 11.91° with the benzothiazole...

The title complex, [Ni(2)(C(11)H(11)Br(2)N(2)O)(2)(NCS)(2)], is a thio-cyanate-bridged dinuclear nickel(II) complex. The asymmetric unit contains two molecules. Both Ni atoms in each molecule have a square-pyramidal coordination geometry, and each center is bound by one O and two N atoms of one Schiff base ligand and by one N atom of a bridging thio-cyanate ligand, which define the basal planes...

The title compound, C(12)H(14)O(6)S, is a dicarboxylic acid diethyl ester of 3,4-ethyl-enedioxy-thio-phene, which is a component of electrically conductive poly(3,4-ethyl-enedioxy-thio-phene) (PEDOT). The ethyl-ene group is disordered over two sites with occupancy factors 0.64 and 0.36. Both the carbonyl groups are coplanar with the thio-phene ring. The mol-ecules form centrosymmetric dimers wi...
