【摘要】 通过 2 ,4,6 三硝基苯酚 (PA)与氢氧化钾溶液反应 ,制备了 2 ,4,6 三硝基苯酚钾 ,并用X射线衍射仪测定了其晶体结构。晶体属正交晶系 ,空间群为Ibca ,晶体学参数为 :a =0 .713 5 ( 1)nm ,b =1.333 2 ( 1)nm ,c =1.912 4( 2 )nm ,V =1.819( 3)nm3,Z =8,Dc=1.95 1g·cm-3 ,μ =13 .4m-1,F( 0 0 0 ) =10 72
【Abstract】 Potassium picrate was prepared from picric acid. Potassium hydrate and its crystal structure was determined by a X ray diffractometer. The results show that the crystal is of orthorhombic system. Space group is Ibca with crystal parameters of a =0.713 5(1) nm, b =1.333 2(1) nm, c = 1.912 4(2) nm , V =1 819.1(3) nm 3 , Z =8, D c=1.951 g·cm -3 , μ =13.4 m -1 , F (000)=1 072.
