    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 3-[2-(3,5-dimethylphenyl)hydrazinylidene]benzofuran- 2(3H)-one
    (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.

    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.
