Fun, H.-K.Ching Kheng, C.K.Malladi, S.Isloor, A.M.Shivananda, K.N.2026-02-052011Acta Crystallographica Section E: Structure Reports Online, 2011, 67, 11, pp. o3102-o310316005368https://doi.org/10.1107/S1600536811044382https://idr.nitk.ac.in/handle/123456789/27147In the title molecule, C<inf>24</inf>H<inf>16</inf>Cl<inf>2</inf>N <inf>2</inf>O, the dihedral angles between the pyrazole ring and its N- and C-bonded phenyl rings are 7.06 (10) and 53.15 (10)°, respectively. The dihedral angle between the two pendant rings is 52.32 (10)°. The molecule exists in a trans conformation with respect to the acyclic C=C bond. In the crystal, inversion dimers occur in which each molecule is linked to the other by two C - H?O hydrogen bonds to the same acceptor O atom. There are also short Cl?Cl contacts [3.3492 (9) Å] and C - H?? interactions. © Fun et al. 2011.
