[Bis-(4-methyl-1,3-thia-zol-2-yl-?N)methane]-tricarbonyl-dichlorido-tungsten(II).

Project description:The title compound, [WCl(2)(C(9)H(10)N(2)S(2))(CO)(3)], is a hepta-coordinate tungsten(II) complex with a capped-octa-hedral coordination sphere in which one CO ligand caps a face formed by a chloro ligand and the two other carbonyls. The chloro ligands are mutually trans positioned at an angle of 156.98?(7)°. The chelating bis-(4-methyl-1,3-thia-zol-2-yl)methane ligand coordinates with the imine N atoms. In the crystal, mol-ecules are linked into chains parallel to [201] by weak C-H?O contacts between the CH(2) group of the bis-(4-methyl-thia-zol-2-yl)methane ligand and the O atom of the capping CO group.

(2E)-2-(1,3-Benzo-thia-zol-2-yl)-3-(di-methyl-amino)-prop-2-ene-nitrile.

Project description:The mol-ecular conformation of title compound, C12H11N3S, is almost planar [maximum deviation = 0.063 (2) Å]; an intra-molecular C-H⋯N hydrogen bond is noted.

Project description:In the title compound, C14H17N3OS2, the central piperidinone ring adopts a chair conformation and the thia-zole rings are inclined to its mean plane by 80.16 (12) and 67.15 (12)°. The O atom and methyl group C atom deviate significantly from the mean plane of the central piperidinone ring, by 0.8138 (2) and 0.3175 (2) Å, respectively. The dihedral angle between the thia-zole rings is 51.88 (13)°. In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds, forming zigzag C(10) chains running parallel to [001].

2-(2-Methyl-phen-yl)-N-(1,3-thia-zol-2-yl)acetamide.

Project description:In the title compound, C12H12N2OS, the dihedral angle between the benzene and thia-zole rings is 83.5?(7)°. The acetamide group is almost coplanar with the thia-zole ring, being twisted from it by 4.2?(9)°. In the crystal, pairs of N-H?N hydrogen bonds link mol-ecules into inversion dimers, generating R 2 (2)[8] loops; the dimers are stacked along [001].

5-Methyl-N-(1,3-thia-zol-2-yl)isoxazole-4-carboxamide.

Project description:In the title compound, C8H7N3O2S, the dihedral angle between the thia-zol and isoxazole rings is 34.08 (13)°. In the crystal, the mol-ecules are linked by pairs of N-H⋯N hydrogen bonds, forming inversion dimers, and C-H⋯O inter-actions, resulting in chains along the b-axis direction.

Polymorphism of bis-(1,3-benzo-thia-zol-2-yl) tri-thio-carbonate.

Project description:The polymorphism of the title compound, C15H8N2S5, is reported, in which the (syn,syn) and (syn,anti) conformers simultaneously crystallized from a chloro-form solution. The complete mol-ecule of the (syn,syn) form is generated by a crystallographic twofold axis. The geometries of both conformers are compared in detail, revealing no significant differences in bond lengths, despite different bond angles because of the conformational changes. Analysis of the inter-molecular inter-actions, aided by Hirshfeld surfaces, shows distinctive S⋯S and S⋯N contacts only for the (syn,anti) conformer. Aromatic π-π-stacking inter-actions are found for both conformers, which occur for the (syn,anti) conformer between pairs of mol-ecules, but are continuous stacks in the (syn,syn) conformer. Non merohedral twinning was found for the crystal of the (syn,anti) conformer used for data collection.

6-Bromo-3-{2-[2-(diphenyl-methyl-ene)hydrazin-yl]-1,3-thia-zol-5-yl}-2H-chromen-2-one chloro-form monosolvate.

Project description:In the title compound, C(25)H(16)BrN(3)O(2)S·CHCl(3), the thia-zole ring is approximately planar [maximum deviation = 0.002 (3) Å] and makes dihedral angles of 10.75 (14) and 87.75 (15)/2.80 (14)° with the pyran ring system and the two terminal phenyl rings, respectively. The solvent mol-ecule is disordered over two sets of sites, with refined occupancies of 0.639 (7) and 0.361 (7). In the crystal, mol-ecules are connected via pairs of weak C-H⋯O inter-actions, forming centrosymmetric dimers. An intra-molecular C-H⋯O hydrogen bond generates an S(6) ring motif.

(E)-Methyl 1,3-thia-zol-2-yl ketone 2,4-dinitro-phenyl-hydrazone.

Project description:Crystals of the title compound, C(11)H(9)N(5)O(4)S, were obtained from a condensation reaction of 2,4-dinitro-phenyl-hydrazine and methyl 1,3-thia-zol-2-yl ketone. Excluding two methyl H atoms, the mol-ecule displays a planar structure, the dihedral angle between the terminal thia-zole and benzene rings being 1.82 (8)°. The imino group links with adjacent nitro and thia-zole groups by intra-molecular bifurcated hydrogen bonding. The centroid-centroid separation of 3.7273 (11) Å between nearly parallel benzene and thia-zole rings of adjacent mol-ecules indicates the existence of π-π stacking in the crystal structure. Weak inter-molecular C-H⋯O hydrogen bonding is also observed.

3-{2-[2-(Diphenyl-methyl-ene)hydrazin-yl]thia-zol-4-yl}-2H-chromen-2-one.

Project description:In the title compound, C(25)H(17)N(3)O(2)S, the coumarin ring system is essentially planar with a maximum deviation of 0.019 (2) Å. A weak intra-molecular C-H⋯O hydrogen bond stabilizes the mol-ecular structure, so that the coumarin plane is approximately coplanar with the thia-zole ring, making a dihedral angle of 2.5 (10)°. The two phenyl rings are nearly perpendicular to each other, with a dihedral angle of 81.44 (12)°. In the crystal structure, the mol-ecules are linked into an infinite chain along the b axis by inter-molecular C-H⋯O hydrogen bonds. Weak C-H⋯π inter-actions are observed between the chains.
