本文报道了8-氯-1H-吡咯并[2，3-B]吩嗪-5-氧化物（1）的合成和晶体结构。化合物1由甲醇中的深色溶液形成深紫色晶体。晶体板属于三斜晶系，P-1空间群，晶胞参数a = 6.9514（8），B= 9.1568（10），c= 10.2067（11），α = 84.509（2），β = 82.936（2），γ = 72.357（2），晶胞体积为613.25（12）A−3。标题化合物含有广泛共轭的吡咯并吩嗪N-氧化物体系的第一个实例，在绿色至青色波长范围内具有强的光吸收，该吸收在质子化后消失。
AbstractThe preparation and crystal structure of 8-chloro-1H-pyrrolo[2,3-b]phenazine5-oxide (1) are described. Compound1formed dark purple crystals from deeply colored solution in methanol. Crystal plates were in the triclinic system,P-1 space group with unit cell parametersa= 6.9514(8),b= 9.1568(10),c= 10.2067(11), α = 84.509(2), β = 82.936(2), γ = 72.357(2) and a cell volume of 613.25(12) A−3. The title compound which contains the first example of the extensively conjugated pyrrolo-phenazine N-oxide system exhibits strong light absorption in the green to cyan wavelength range which disappears upon protonation.Graphical AbstractThe synthesis, optical properties and crystal structure of the title compound is described.
