The mol-ecular skeleton of the title mol-ecule, C(16)H(11)NO(3), is nearly planar with the two aromatic rings forming a dihedral angle of 2.73 (7)°. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules into ribbons extended along [101]. The crystal packing exhibits also π-π inter-actions, as indicated by the short centroid-centroid distances between the aromatic rings [3.68...

In the title pyrimidine derivative, C(23)H(23)N(3)S(2), the phenyl-sulfanyl and benzyl-sulfanyl benzene rings are orientated away from the carbonitrile group and are twisted out of the plane of the central ring with dihedral angles of 77.66 (6) and 64.73 (5)°, respectively. The n-pentyl group has an extended trans conformation. In the crystal, supra-molecular layers in the ab plane are sustaine...

In the title compound, C(19)H(16)F(3)N(3), the dihedral angle between the naphthalene and quinoline ring systems is 14.58 (8)°. The hydrazone C-N-N=C-C chain is in an extended conformation and its mean plane is nearly coplanar with the quinoline plane [dihedral angle = 3.45 (9)°]. The bond angles within the phenyl ring show the almost additive influence of the two para substituents. In the crys...

The title compound, C(26)H(18)N(4)O(5), can be regarded as an extended ether with two terminal nitro groups. The two aryl rings bonded to the central O atom form a dihedral angle of 75.72 (6)°, and the terminal nitro groups are slightly twisted [by 6.4 (2) and 3.3 (3)°] from the benzene rings to which they are attached. The crystal packing exhibits weak inter-molecular C-H⋯O hydrogen bonds and ...

The title compound, C9H10O3, is a bioactive secondary metabolite, isolated from the endophytic fungus Nodulisporium sp. The compound exhibits an intra-molecular O-H⋯O hydrogen bond between the phenolic H atom and the carbonyl O atom of the adjacent acetyl group. In the crystal, mol-ecules are linked by hydrogen bonds involving the 4-phenolic H atom and a symmetry-related carbonyl O atom of a ne...

The title compound, C(12)H(10)N(4)O(2)·H(2)O, was synthesized by the reaction of pyrazine-2-carboxylic acid hydrazide and 3-hydroxy-benzaldehyde in ethanol. In the crystal structure, the organic mol-ecules are linked into extended chains by inter-molecular N(amide)-H⋯O(hydr-oxy) hydrogen bonds. Additional hydrogen bonds between the water mol-ecule and three adjacent organic mol-ecules, as well ...

In the title compound, C15H15NO4S, the dihedral angle between the aromatic rings is 80.81 (1)° and the dihedral angle between the planes defined by the S-N-C=O fragment and the sulfonyl benzene ring is 86.34 (1)°. In the extended structure, dimers related by a crystallographic twofold axis are connected by pairs of both N-H⋯O hydrogen bonds and C-H⋯O inter-actions, which generate R 2 (2)(8) and...

In the crystal structure of the title compound, C(20)H(23)Br(2)N, the octyl chains are extended in an anti conformation and form a segregating bilayer, isolating rows of carbazole units. The carbazole moieties are engaged in offset π-π inter-actions; the smallest centroid-to-centroid distance is 4.2822 (11) Å. This offset packing motif allows the methyl-ene group attached directly to the N atom...

The title compound, C(32)H(18)F(4)N(4)S(2), is a disulfide symmetric-ally substituted with two diaza-meta-terphenyl groups. In the crystal, the mol-ecule adopts a twisted conformation with a C-S-S-C torsion angle of -91.82 (7)°. One of the 4,6-(4-fluoro-phen-yl)pyrimidine groups is virtually planar, with dihedral angles between the pyrimidine and benzene groups of 4.00 (8) and 5.44 (8)°, wheare...

The mol-ecule of the title compound, C(25)H(34)N(2)O(6), adopts a fully extended configuration. The oxime (-CH=N-O-) group is coplanar with the aromatic ring and the two benzene rings are almost parallel, making a dihedral angle of 0.16 (3)°. In the crystal structure, strong intra-molecular O-H⋯N hydrogen bonds generate six-membered S(6) ring motifs. Inter-molecular C-H⋯O hydrogen bonds link ea...
