    (2021) Atioğlu, Zeliha; Akkurt, Mehmet; Shikhaliyev, Namiq Q.; Askerova, Ulviyya F.; Niyazova, AA; Mlowe, Sixberth
    In the title compound, C16H12F5N3O, the dihedral angle between the aromatic rings is 31.84?(8)°. In the crystal, the molecules are linked into dimers possessing crystallographic twofold symmetry by pairwise N—H?O hydrogen bonds and weak C—H?O hydrogen bonds and aromatic ?–? stacking interactions link the dimers into a three-dimensional network. A Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from F?H/H?F (41.1%), H?H (21.8%), C?H/H?C (9.7%) C?C (7.1%) and O?H/H?O (7.1%) contacts. The contribution of some disordered solvent to the scattering was removed using the SQUEEZE routine [Spek (2015). Acta Cryst. C71, 9–18] in PLATON. The solvent contribution was not included in the reported molecular weight and density.

    (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.

    In the molecule of the title compound, C22H14Cl4N4, the central benzene ring makes dihedral angles of 77.03?(9) and 81.42?(9)° with the two approximately planar 2,2-dichloro-1-[(E)-phenyldiazenyl]vinyl groups. In the crystal, molecules are linked by C—H??, C—Cl??, Cl?Cl and Cl?H interactions, forming a three-dimensional network.

    (2021) Atioğlu, Zeliha; Akkurt, Mehmet; Shikhaliyev, Namiq Q.; Askerova, Ulviyya F.; Mukhtarova, Sevinc H.; Askerov, Rizvan K.; Bhattarai, Ajaya
    In the title compound, C16H14N2O2, the 2,3-dihydro-1-benzofuran ring system is essentially planar and makes a dihedral angle of 3.69 (7) with the dimethylphenyl ring. The molecular conformation is stabilized by an intramolecular N— H O hydrogen bond with an S(6) ring motif. In the crystal, molecules are connected by C—H and – stacking interactions, forming a layer lying parallel to the (111) plane. One methyl group is disordered over two orientations, with occupancies of 0.67 (4) and 0.33 (4). Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from H H (51.2%), O H/H O (17.9%), C H/H C (15.2%) and C C (8.1%) contacts.

    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.

    Crystal structure and Hirshfeld surface analysis of a new polymorph of (E)-2-(4-bromo­phen­yl)-1-[2,2-di­bromo-1-(3-nitro­phen­yl)ethen­yl]diazene
    (2022) Atioğlu, Zeliha; Akkurt, Mehmet; Shikhaliyev, Namiq Q.; Mammadova, N. A.; Mammadova, Naila A.; Babayeva, Gülnara V.; Khrustalev, Victor N.; Bhattarai, Ajaya
    A new polymorph of the title compound, C14H8Br3N3O2, (form-2) was obtained in the same manner as the previously reported form-1 [Akkurt et al. (2022[Akkurt, M., Yıldırım, S. Ö., Shikhaliyev, N. Q., Mammadova, N. A., Niyazova, A. A., Khrustalev, V. N. & Bhattarai, A. (2022). Acta Cryst. E78, 732-736.]). Acta Cryst. E78, 732–736]. The structure of the new polymorph is stabilized by a C—H?O hydrogen bond that links mol­ecules into chains. These chains are linked by face-to-face ?–? stacking inter­actions, resulting in a layered structure. Short inter-mol­ecular Br?O contacts and van der Waals inter­actions between the layers aid in the cohesion of the crystal packing. In the previously reported form-1, C—H?Br inter­actions connect mol­ecules into zigzag chains, which are linked by C—Br?? inter­actions into layers, whereas the van der Waals inter­actions between the layers stabilize the crystal packing of form-2. Hirshfeld mol­ecular surface analysis was used to compare the inter­molecular inter­actions of the polymorphs.

    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.
