Abstract: The crystal structure of B-Si pentasil zeolite molecular sieves has been determined by means of the X-ray diffraction for polycrystalline materials and has been refined with Rietvelds method. The parameters ofthe cell are : a= 19.983(1)Å; b= 19.973(1) Å; c= 13.303(1)Å. Its space group is D2h16-Pnma, The framework topology found agrees with reported Si-Al ZSM-5 zeolite molecular sieves. It is concluded from the structure detemination that Bis introduced into the framework of this sample.
