    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)-1-[2,2-dichloro-1-(4-methylphenyl)ethenyl]-2- (4-methoxyphenyl)diazene
    (2021) Shikhaliyev, Namiq Q.; Atioğlu, Zeliha; Akkurt, Mehmet; Qacar, Ayten M.; Askerov, Rizvan K.; Bhattarai, Ajaya
    The asymmetric unit of the title compound, C16H14Cl2N2O, comprises two similar molecules, A and B, in which the dihedral angles between the two aromatic rings are 70.1 (3) and 73.2 (2) , respectively. The crystal structure features short C—H Cl and C—H O contacts and C—H and van der Waals interactions. The title compound was refined as a two-component nonmerohedral twin, BASF 0.1076 (5). The Hirshfeld surface analysis and twodimensional fingerprint plots show that H H (38.2% for molecule A; 36.0% for molecule B), Cl H/H Cl (24.6% for molecule A; 26.7% for molecule B) and C H/H C (20.0% for molecule A; 20.2% for molecule B) interactions are the most important contributors to the crystal packing.

    Crystal structure and Hirshfeld surface analysis of 1, 3-bis {2, 2-dichloro-1-[(E)-phenyldiazenyl] ethenyl} benzene
    (2021) Shikhaliyev, Namiq Q.; Atioğlu, Zeliha; Akkurt, Mehmet; Ahmadova, Nigar E.; Askerov, Rizvan K.; Bhattarai, Ajaya
    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. The Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from H?H (30.4%), C?H/H?C (20.4%), Cl?H/H?Cl (19.4%), Cl?Cl (7.8%) and Cl?C/C?Cl (7.3%) interactions.

    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.
