介绍了从晶体粉末Ｘ射线衍射数据确定其晶胞参数的方法，并用该法求得四方体心晶体结构的锂铜酞花菁ＬｉＣｕＰｃ的晶胞参数ａ＝１．７３６７ｎｍ，ｃ＝１．３６４０ｎｍ；三方晶系Ｒ３ｍ空间群结构的锂钴氧化合物Ｌｉ０．５ＣｏＯ２按六方格子划分的晶胞参数ａ＝０．２８０８ｎｍ，ｃ＝１．４０７９ｕｍ．
A method to determine the unit cell parameters from crystal powder X - ray diffraction data is introduced. The cell parameters of lithium copper phthalocyanine LiCuPc obtained by this method are a = 1.7367nm and c = 1.3640nm, respectively. The unit cell parameters a = 0.2808nm and c = 1.4079um of lithium cobalt oxide Li0.5CoO2 divided by hexagonal lattice in the cubic system R3m space group structure.
