Project description:The title compound, C(12)H(14)ClN(3), represents the planar azoenamine tautomer. The benzene ring forms a dihedral angle of 2.5 (1)° with the azoenamine group. Electron delocalization is indicated by the values of the bond lengths in the chain. The tetra-hydro-pyridine ring adopts a half-chair conformation and the dihedral angle between the least-squares plane defined by the five coplanar C atoms and the azoenamine unit is 2.0 (1)°, while the envelope-flap C atom lies out of this plane by 0.579 (2) Å. The mol-ecular packing is governed by van der Waals inter-actions through the stacking of adjacent mol-ecules, resulting in a two-dimensional sheet structure.

Project description:The title compound, [Pt(C(13)H(10)ClN(2)S)Cl], contains a Pt atom tetra-coordinated by a benzene C, a diazene N, a Cl and an S atom in an approximately square-planar geometry. The mol-ecules dimerize through a nonbonded S⋯S inter-action [S⋯S = 3.523 (18) Å]. There are no hydrogen bonds and the crystal packing is stabilized by four inter-molecular π-π inter-actions; the centroid-centroid distances are 3.804 (3), 3.638 (3), 3.804 (3) and 3.638 (3) Å, and the corresponding perpendicular distances are 3.369, 3.448, 3.406 and 3.466 Å.

Project description:The structure of the title complex, [ZnCl2(C11H9N3)2], comprises two 2-(phenyl-diazen-yl)pyridine ligands coordin-ating to a central Zn(II) dichloride unit via the pyridyl N-atom donors, resulting in a slightly distorted tetra-hedral geometry. The complex exhibits twofold rotation symmetry, with the rotation axis bis-ecting the zinc cation. The structure is stabilized by weak inter-molecular C-H?Cl inter-actions [C?Cl = 3.411?(2) and 3.675?(2)?Å], connecting neighbouring mol-ecules into layers perpendicular to the c axis.

Project description:THE TITLE COMPOUND [SYSTEMATIC NAME: (E)-2-hy-droxy-5-(phenyl-diazen-yl)cyclo-hepta-2,4,6-trien-1-one], C(13)H(10)N(2)O(2), is essentially planar with an r.m.s. deviation of 0.036 (2) Å and a dihedral angle of 1.57 (8)° between the phenyl and tropolone rings. In the crystal, mol-ecules are linked by pairs of O-H⋯O hydrogen bonds into inversion dimers. The dimers are further connected by C-H⋯O hydrogen bonds and π-π stacking inter-actions, with centroid-centroid distances of 3.6934 (9) and 3.6282 (9) Å.

Project description:The crystal structure of the title compound, C(14)H(14)N(2)O, determined at 100 K, shows that the mol-ecules are not planar in the solid state, in contrast to other diazene (azobenzene) derivatives. The dihedral angle between the planes of the two aromatic rings is 42.32 (7)°. The mol-ecules are linked by inter-molecular O-H⋯N hydrogen bonds, forming an infinite one-dimensional chain.

Project description:The crystal structure of the title compound, C(14)H(11)ClN(2)O(2)S, features a three-dimensional network stabilized by ?-? inter-actions between the rings of the 4-methyl-phenyl-sulfonyl protecting group [centroid-centroid distance = 3.623?(1)?Å]. The 4-methyl-phenyl-sulfonyl ring makes a dihedral angle of 79.60?(6)° with the 4-chloro-1H-pyrrolo[2,3-b]pyridine unit.

Project description:The title compound, C(18)H(12)N(6)O(6), was prepared from the reaction of 4-(phenyl-diazen-yl)aniline (aniline yellow) with picryl-sulfonic acid. The dihedral angle formed by the two benzene rings of the diphenyl-diazenyl ring system is 6.55?(13)° and that formed by the rings of the picrate-aniline ring system is 48.76?(12)°. The mol-ecule contains an intra-molecular aniline-nitro N-H?O hydrogen bond.

Project description:In the title mol-ecule, C(16)H(15)N(3), the indole ring system is planar within 0.021 (3) Å and the phenyl ring is inclined to this plane by 17.32 (14)°. π-π contacts involving the pyrrole rings of inversion-related indole units [centroid-centroid distance = 3.5187 (17) Å] stabilize the crystal structure.

Project description:The title compound, C(13)H(12)ClN(3)O, exhibits a trans geometry about the N=N double bond in the solid state. The dihedral angle between the rings is 22.20?(8)°. Inter-molecular N-H?O hydrogen bonds between the amine and meth-oxy groups lead to the formation of a chain-like polymer along the c axis with a C(6) graph set. There is also weak non-classical C-H?N hydrogen bonds involving an aromatic C-H group and a diazenyl N atom, which connect the chains into a two-dimensional framework.

Project description:The title compound, C(19)H(15)ClN(2)S, a divalent organosulfur compound belonging to the class of ortho-mercaptoazo compounds, is non-ionic in nature. The azo group in the mol-ecule is moved away from the S atom to attain the stable trans-azo configuration. Here the S atom is not electron deficient, so no intra-molecular N?S inter-action exists. Due to steric reasons, the mol-ecule is non-planar: the chlorophenyl and benzyl rings are oriented at dihedral angles of 3.21?(8) and 78.18?(5)°, respectively, with respect to the thiophenyl ring. There are no hydrogen bonds and the crystal structure is stabilized by van der Waals inter-actions.
