    2-(6-Oxo-3,4-diphenyl-1,6-dihydro-pyridazin-1-yl)acetic acid
    (2007-11-09) Aydin A., Doǧruer D., Akkurt M., Büyükgüngör O.; Aydin, A, Dogruer, DS, Akkurt, M, Buyukgungor, O
    In the title compound, C18H14N2O3, the pyridazine ring makes dihedral angles of 72.73 (11) and 49.97 (10)° with the two phenyl rings. The dihedral angle between the two phenyl rings is 52.42 (12)°. The crystal structure is stabilized by inter-molecular O - H⋯O and C - H⋯O hydrogen-bonding inter-actions. © International Union of Crystallography 2007.

    2-[2-(4-Benzyl-piperazin-1-ylcarbon-yl)eth-yl]-5,6-diphenyl-pyridazin-3(2H) -one
    (2008-12-12) Aydn A., Doruer D.S., Akkurt M., Büyükgüngör O.; Aydin, A, Dogruer, DS, Akkurt, M, Buyukgungor, O
    The title compound, C30H30N4O2, has a non-planar conformation, the dihedral angles formed by the pyridazinone ring plane and the three phenyl rings being 54.61 (7), 51.10 (7) and 59.53 (8)°. The piperazine ring adopts a chair conformation. Inter- and intra-molecular C - H⋯O contacts are found in the crystal structure and these consolidate the three-dimensional packing.
