    (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.

    In the cation of the title salt, C30H28NO2 + CF3O3S , the four tetrahydrofuran rings adopt envelope conformations. In the crystal, pairs of cations are linked by dimeric C—H O hydrogen bonds, forming two R2 2(6) ring motifs parallel to the (001) plane. The cations and anions are connected by further C—H O hydrogen bonds, forming a three-dimensional network structure. Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from H H (47.6%), C H/H C (20.6%), O H/H O (18.0%) and F H/H F (9.9%) interactions.

    The molecule of the title compound, C24H16Cl12N2O4, is generated by a crystallographic inversion centre at the midpoint of the central C—C bond. A kink in the molecule is defined by a torsion angle of ?169.86?(15)° about this central bond of the alkyl bridge. The pyrrolidine ring is essentially planar [max. deviation = 0.014?(1)?Å]. The cyclohexane ring has a boat conformation, while both cyclopentane rings adopt an envelope conformation. In the crystal structure, molecules are linked by intermolecular C—H?O, C—H?Cl and C—Cl?? interactions, and short intermolecular Cl?O and Cl?Cl contacts, forming a three-dimensional network.

    Crystal structure and Hirshfeld surface analysis of (3Z)-7-meth­­oxy-3-(2-phenyl­hydrazinyl­­idene)-1-benzo­furan-2(3H)-one
    (2021) Atioğlu, Zeliha; Akkurt, Mehmet; Askerova, Ulviyya F.; Mukhtarova, Sevinc H.; Askerov, Rizvan K.; Mlowe, Sixberth
    In the title compound, C15H12N2O3, pairs of mol­ecules are linked into dimers by N—H?O hydrogen bonds, forming an R22(12) ring motif, with the dimers stacked along the a axis. These dimers are connected through ?–? stacking inter­actions between the centroids of the benzene and furan rings of their 2,3-di­hydro-1-benzo­furan ring systems. Furthermore, there exists a C—H?? inter­action that consolidates the crystal packing. A Hirshfeld surface analysis indicates that the most important contacts are H?H (40.7%), O?H/H?O (24.7%), C?H/H?C (16.1%) and C?C (8.8%).

    Crystal structure and Hirshfeld surface analysis of (E)-4-({2,2-di­chloro-1-[4-(di­methyl­amino)­phen­yl]ethenyl}diazen­yl)benzo­nitrile

    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.

    (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.
