| 摘 要： | The title compound, 2,6-bis（benzimidazo（1,2-c）quinazolin-6-yl）pyridine tetrahydrate, was synthesized by simple condensation of 2-（2-sminophenyl） benzimidazole with pyfidine- 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）A, β = 115.796（13）°, V = 5631（4）A^3, C33H27NTO4, Mr = 585.62, Z = 8, Dc = 1.381 g/cm^3, λ（MoKα） = 0.71073 A, 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 A） are pronounced in the crystal structure.

| Abstract: | 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) (A°),β = 115.796(13)°, V = 5631 (4)(A°)3, C33H27N7O4, Mr= 585.62, Z = 8, Dc= 1.381 g/cm3, λ(MoKa) = 0.71073 (A°), 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 A) are pronounced in the crystal structure. |
