A new series of 11-pyridyl substituted dibenzo-diazepin-1-one derivatives 1 was synthesized by a two step cyclocondensation reaction. All the compounds were characterized by IR, MS, and ¹H NMR. And crystals of 1a and 1b were obtained and determined by X-ray single-crystal diffraction. Crystal data of 1a: C₄₈H₅₂N₆O₇, monoclinic system, space group C2/c, a=28.39(4), b=9.275(12), c=16.84(2)Å, β=104.98(3)°, V=4284(10)Å³, Z=4, F(000)=1752, D_c=1.279 g/cm³, R=0.0603, and wR=0.1314. Crystal data of 1b: C₂₄H₂₁N₃O, monoclinic system, space group P2₁/c, a=11.625(5), b=19.055(9), c=8.741(4)Å, β=95.547(6)°, V=1927.2(15)Å³, Z=4, F(000)=776, D_c=1.266 g/cm³, R=0.0494, and wR=0.1287.
