The asymmetric unit of the title compound, C(17)H(10)FN(3)OS, consists of two crystallographically independent mol-ecules. In one mol-ecule, the pyrazole ring makes dihedral angles of 6.51 (7) and 34.02 (9)°, respectively, with the terminal 1,3-benzothia-zole ring system and the phenyl ring, while in the other mol-ecule these values are 6.41 (8) and 23.06 (9)°. In the crystal, the molecules are...

The title compound, C17H12O, crystallized with three independent mol-ecules (A, B and C) in the asymmetric unit. In the crystal, the three independent mol-ecules are linked by π-π inter-actions [centroid-centroid distances = 3.551 (3)-3.977 (2) Å], which lead to the formation of trimers. Between the trimers there are a number of C-H⋯π inter-actions generating a laminar arrangement parallel to (...

The asymmetric unit of the title compound, [Cu(C(9)H(9)O(4))(2)(C(12)H(8)N(2))], contains one half-mol-ecule, the complete mol-ecule being generated by a twofold rotation axis. The Cu(II) atom exhibits a six-coordinated distorted octa-hedral geometry with two N atoms from the phenanthroline ligand [Cu-N 2.007 (2) Å] and four O atoms from two 3,4-dimethoxy-benzoate ligands [Cu-O 1.950 (1) and 2....

The mol-ecule of the title compound, C(14)H(9)NO(2)S, is nearly planar, the maximum atomic deviation being 0.081 (2) Å. An intra-molecular O-H⋯N bond generates an S(6) ring motif. In the crystal, inversion-related mol-ecules linked by a pair of weak C-H⋯O hydrogen bonds form a supra-molecular dimer. π-π stacking is observed between the thia-zole and benzene rings of adjacent mol-ecules, the cen...

In the title mol-ecule, C(25)H(19)N(3)O(3)S(3), the tetra-hydro-pyridine ring adopts a half-chair conformation. The dihedral angle between the least-squares plane through the tetra-hydro-pyridine ring and two thio-phene and two benzene rings are 6.25 (9), 89.49 (9), 76.43 (9) and 84.93 (8)°, respectively, while the dihedral angle between the 1,3,4-oxadiazole and tetra-hydro-pyridine rings is 81...

The asymmetric unit of the title compound, C(14)H(13)BrN(2)O, consists of two mol-ecules; the dihedral angles between the pyridine and benzene rings are 87.99 (9) and 84.28 (9)°. An intra-molecular C-H⋯O hydrogen bond generates an S(6) ring in each mol-ecule. In the crystal, mol-ecules are linked via N-H⋯N and C-H⋯O hydrogen bonds into a three-dimensional network. The crystal structure also fea...

In the title compound, C(10)H(10)N(4)O(5)S·C(9)H(9)N(3)O(5), the amide groups of 3-(3,5-dinitro-benzo-yl)-1,1-dimethyl-thio-urea and N,N-dimethyl-3,5-dinitro-benzamide mol-ecules are oriented at dihedral angles of 39.13 (8) and 55.97 (11)°, respectively, to the attached benzene rings. In the crystal, the two mol-ecules are linked by an N-H⋯O hydrogen bond. Weak C-H⋯O link the mol-ecules into a ...

The asymmetric unit of title compound, C(8)H(6)O(4)·2C(4)H(9)NO, contains one half-mol-ecule (an inversion centre in P21/n generates the other half of the molecule) of terephthalic acid (TA) and one mol-ecule of N,N-dimethyl-acetamide (DMAC). The DMAC mol-ecules are linked to TA by strong O-H⋯O hydrogen bonds.

In the title compound, C(9)H(13)NO(2), there are two independent mol-ecules per asymmetric unit. The mol-ecules are very similar and almost planar, with the ethoxy-carbonyl group anti to the pyrrole N atom. The two independent mol-ecules are joined into dimeric units by strong hydrogen bonds between NH groups and carbonyl O atoms.
