5-(Phenyl-diazen-yl)tropolone.

ABSTRACT: 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.

Crystal structure of 5-[2-(2,4,6-tri-bromo-phen-yl)diazen-yl]tropolone.

Project description:The title compound {systematic name: 2-hy-droxy-5-[2-(2,4,6-tri-bromo-phen-yl)diazen-1-yl]cyclo-hepta-2,4,6-trien-1-one}, C13H7Br3N2O2, is essentially planar, with an r.m.s. deviation of 0.054?Å. The mol-ecular structure is fixed in the azo tautomer by intra-molecular C-H?N inter-actions, with O-H?O hydrogen bonds creating linked dimers. Charge-transfer inter-actions are observed, with the segregated stacks linked by Br?Br inter-actions.

1-[(E)-4-(Phenyl-diazen-yl)phen-yl]-3-pyrroline-2,5-dione.

Project description:The title compound, C(16)H(11)N(3)O(2), displays a trans configuration with respect to the azo group. The mol-ecule is non-planar; the maleimide ring forms a dihedral angle of 42.35 (4)° with the benzene ring bonded to its N atom and the mean plane of this benzene ring is rotated by 21.46 (8)° with respect to the azo group mean plane, which, in turn, forms a dihedral angle of 24.48 (7)° with the 'terminal' benzene ring. Mol-ecules in the crystal are π-π stacked along the [100] direction with a mean inter-planar distance of 3.857 (1) Å. In addition, C-H⋯O inter-actions link them into double layers parallel to the ac plane.

Chlorido{5-chloro-2-[2-(methyl-sulfanyl)phenyl-diazen-yl]phenyl}-platinum(II).

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.

(E)-4-[(4-Nitro-phen-yl)diazen-yl]phenyl anthracene-9-carboxyl-ate.

Project description:In the title compound, C(27)H(17)N(3)O(4), the azo group displays a trans conformation and the dihedral angles between the central benzene ring and the pendant anthracene and nitro-benzene rings are 82.94 (7) and 7.30 (9)°, respectively. In the crystal structure, weak C-H⋯O hydrogen bonds, likely associated with a dipole moment present on the mol-ecule, help to consolidate the packing.

1-(4-Cyano-phenyl-diazen-2-ium-1-yl)-2-naphtholate.

Project description:In the mol-ecule of the zwitterionic title compound, C(17)H(11)N(3)O, the naphthalene ring system is planar [maximum deviation = 0.029?(3)?Å] and is oriented at a dihedral angle of 3.55?(3)° with respect to the benzene ring.
