The title compound, 2,6-bis(benzimidazo(1,2-c)quinazolin-6-yl)pyridine tetrahy- drate, was synthesized by simple condensation of 2-(2-sminophenyl) benzimidazole with pyridine-2,6-dicarboxylic acid and characterized by elemental analysis, IR spectra and single-crystal X-ray diffraction. The crystal belongs to the monoclinic system, space group C2/c with a = 22.226(8), b = 16.730(7), c = 16.820(5) , β = 115.796(13)o, V = 5631(4) 3, C33H27N7O4, Mr = 585.62, Z = 8, Dc = 1.381 g/cm3, λ(MoKα) = 0.71073 , F(000) = 2448 and μ = 0.09 mm-1. The structure was refined to the final R = 0.0730 and wR = 0.1573 for 6346 independent reflections (Rint = 0.0801) and 3384 observed reflections (I > 2σ(I)). In the crystal, the molecules are linked through intermolecular O-H…O and O-H…N hydrogen bonds. Intermolecular π-π interactions (with distances of about 3.45) are pronounced in the crystal structure.
