Abstract: In this paper, the refined X-ray powder diffraction pattern and its indices werepresented according to the requirements on ah initio structure determination from powderdiffraction data. Instrumental conditions, sample preparation methods and standardreference materials' application were discussed. The questions and solutions on indexing had beensummed up. The refined unit cell parameters for orthorhomblc system of the title compoundare: a=1. 3710(1) um, b=1. 0715(1) um, c=0. 6947(1) um, V=1. 0206(1)nm3, Z=4,Dx= 2.50g·cm-3, F30=81. (0.0071, 52), M20=41. Extinction conditions indicate that thespace group is Puma or Pn21a.
