    (2005) Caira, Mino R; Dumitrascu, Florea; Draghici, Constantin; Dumitrescu, Denisa; Cristea, Mihaela
    The synthesis, characterization and X-ray crystal structure of 2-(4-chloro-phenyl)-7-methylpyrrolo[1,2-b]pyridazine are reported. The compound crystallizes in the space group P21/c (No.14) with a =3.8568(1), b = 11.0690(3), c = 26.4243(7) Å, β = 92.777(1)° and Z = 4. Accurate molecular parameters for the novel heterocyclic system were obtained from intensity data collected at 113K. The molecule assumes a planar conformation in the crystal and the packing is based on π-π stacking with interplanar spacing 3.400 Å, typical of aromatic molecules with potential for displaying useful optical properties.
