Crystal structure and Hirshfeld surface analysis of (E)-1-[2,2-di-chloro-1-(4-fluoro-phen-yl)ethen-yl]-2-(2,4-di-chloro-phen-yl)diazene.

ABSTRACT: In the title compound, C₁₄H₇Cl₄FN₂, the dihedral angle between the 4-fluoro-phenyl ring and the 2,4-di-chloro-phenyl ring is 46.03 (19)°. In the crystal, the mol-ecules are linked by C-H⋯N inter-actions along the a-axis direction, forming a C(6) chain. The mol-ecules are further connected by C-Cl⋯π inter-actions and face-to-face π-π stacking inter-actions, forming ribbons along the a-axis direction. Hirshfeld surface analysis indicates that the greatest contributions to the crystal packing are from Cl⋯H/H⋯Cl (35.1%), H⋯H (10.6%), C⋯C (9.7%), Cl⋯Cl (9.4%) and C⋯H/H⋯C (9.2%) inter-actions.

Project description:In the two isotypic title compounds, C14H8BrCl2N3O2, (I), and C14H8Cl3N3O2, (II), the substitution of one of the phenyl rings is different [Br for (I) and Cl for (II)]. Aromatic rings form dihedral angles of 60.9 (2) and 64.1 (2)°, respectively. Mol-ecules are linked through weak X⋯Cl contacts [X = Br for (I) and Cl for (II)], C-H⋯Cl and C-Cl⋯π inter-actions into sheets parallel to the ab plane. Additional van der Waals inter-actions consolidate the three-dimensional packing.

Crystal structure and Hirshfeld surface analysis of (E)-2-(4-bromo-phen-yl)-1-[2,2-di-bromo-1-(4-nitro-phen-yl)ethen-yl]diazene.

Project description:The mol-ecule of the title compound, C14H8Br3N3O2, consists of three almost planar groups: the central di-bromo-ethenyldiazene fragment and two attached aromatic rings. The mean planes of these rings form dihedral angles with the plane of the central fragment of 26.35 (15) and 72.57 (14)° for bromine- and nitro-substituted rings, respectively. In the crystal, C-H⋯Br inter-actions connect mol-ecules, generating zigzag C(8) chains along the [100] direction. These chains are linked by C-Br⋯π inter-actions into layers parallel to (001). van der Waals inter-actions between the layers aid in the cohesion of the crystal packing. The most substantial contributions to crystal packing, according to a Hirshfeld surface analysis, are from Br⋯H/H⋯Br (20.9%), C⋯H/H⋯C (15.2%), O⋯H/H⋯O (12.6%) and H⋯H (11.7%) contacts.
