    Crystal structure and Hirshfeld surface analysis of (E)-1-[2,2-di­chloro-1-(4-nitro­phen­yl)ethen­yl]-2-(4-fluoro­phen­yl)diazene
    (2019) Atioğlu, Zeliha; Akkurt, Mehmet; Shikhaliyev, Namiq Q.; Suleymanova, Gulnar T.; Bagirova,Khanim N.; Toze, A. A. Flavien
    In the title compound, C14H8Cl2FN3O2, the 4-fluoro­phenyl ring and the nitro-substituted benzene ring form a dihedral angle of 63.29?(8)°. In the crystal, mol­ecules are linked by C—H?O hydrogen bonds into chains running parallel to the c axis. The crystal packing is further stabilized by C—Cl??, C—F?? and N—O?? inter­actions. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions to the crystal packing are from H?O/O?H (15.5%), H?H (15.3%), Cl?H/H?Cl (13.8%), C?H/H?C (9.5%) and F?H/H?F (8.2%) inter­actions.

    Crystal structure and Hirshfeld surface analysis of (E)-4-({2,2-di­chloro-1-[4-(di­methyl­amino)­phen­yl]ethenyl}diazen­yl)benzo­nitrile
    (2021) Shikhaliyev, Namiq Q.; Atioğlu, Zeliha; Akkurt, Mehmet; Suleymanova, Gulnar T.; Babayeva, Gulnare V.; Mlowe, Sixberth
    In the title compound, C17H14Cl2N4, the dihedral angle between the aromatic rings is 50.09?(9)°. The central –N=N– unit shows an E configuration. In the crystal, C—H?N inter­actions, C—Cl?? and ?–? stacking inter­actions [centroid-to-centroid distance = 3.7719?(14)?Å] link the mol­ecules, forming mol­ecular layers approximately parallel to the (002) plane. Additional weak van der Waals inter­actions between the layers consolidate the three-dimensional packing. Hirshfeld surface analysis indicates that the most important contributions for the crystal packing are from H?H (33.6%), N?H/ H?N (17.2%), Cl?H/H?Cl (14.1%) and C?H/H?C (14.1%) contacts.

    Crystal structure and Hirshfeld surface analysis of 4-{2,2-dichloro-1-[(E)-(4-chlorophenyl)diazenyl]- ethenyl}-N,N-dimethylaniline
    (International Union of Crystallography, 2020) Toze, A. A. Flavien; Suleymanova, Gulnar T.; Mukhtarova, Sevinc H.; Shikhaliyev, Namiq Q.; Akkurt, Mehmet; Atioğlu, Zeliha
    The title compound, C16H14Cl3N3, comprises three mol­ecules of similar shape in the asymmetric unit. The crystal cohesion is ensured by inter­molecular C—H?N and C—H?Cl hydrogen bonds in addition to C—Cl?? inter­actions. Hirshfeld surface analysis and two-dimensional fingerprint plots reveal that Cl?H/H?Cl (33.6%), H?H (27.9%) and C?H/H?C (17.6%) are the most important contributors towards the crystal packing.

    (E)-1-(2,6-Dichlorophenyl)-2-(3-nitrobenzylidene)hydrazine: crystal structure and Hirshfeld surface analysis
    (2020) Atioğlu, Zeliha; Akkurt, Mehmet; Shikhaliyev, Namiq Q.; Suleymanova, Gulnar T.; Babayeva, Gulnare V.; Gurbanova, Nurana V.; Mammadova, Gunay Z.; Mlowe, Sixberth
    The stabilized conformation of the title compound, C13H9Cl2N3O2, is similar to that of the isomeric compound (E)-1-(2,6-dichlorophenyl)-2-(2-nitrobenzylidene) hydrazine. The 2,6-dichlorophenyl ring and the nitro-substituted benzene ring form a dihedral angle of 26.25 (16) . In the crystal, face-to-face - stacking interactions along the a-axis direction occur between the centroids of the 2,6- dichlorophenyl ring and the nitro-substituted benzene ring. The molecules are further linked by C—H O contacts and N—H O and C—H Cl hydrogen bonds, forming pairs of hydrogen-bonded molecular layers parallel to (100). The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions to the crystal packing are from H H (22.1%), Cl H/ H Cl (20.5%), O H/H O (19.7%), C C (11.1%) and C H/H C (8.3%) interactions.
