【摘要】 采用Ｘ射线粉末衍射法对Ｌ－精氨酸·氟硼酸加合物进行了分析。数据收集范围在２θ角从７°到８０°（共６４个观测点）。采用最小二乘法对该加合物粉末衍射的晶胞参数进行了计算，实验表明：该加合物为正交晶系，空间群Ｐ２１２１２１，晶胞参数α＝０．５０７０２（６）ｎｍ，ｂ＝１．３７２８８（１２）ｎｍ，ｃ＝１．６４８８０（１５）ｎｍ，Ｖ＝１．１４７７１３ｎｍ３；Ｚ＝４；ρ＝１．５２ ｇ／ｃｍ３，粉末衍射分析的结果与单晶结构数据相吻合。更多还原

【Abstract】 An adduct L - arginine fluoroborate(LAFB, C3H15BF4N4O2) has been characterized by X - ray powder diffraction. The X - ray powder diffraction data of LAFB were given in the range of 2 θfrom 7°to 80°.The crystal structure data of LAFB were calculated by least square method. The results obtaind show that LAFB crystal belongs in orthorhomic system. Its crystal structure data are as follows: α= 0. 507 02 (6)nm, b = 1.372 88(12) nm, c = 1.648 80(15) nm, V= 1. 147 71 nm3; Z = 4; P = 1.52 g/cm3 and space group P212121. The powder diffraction results are in agreement with those obtained from single crystal X- ray diffraction.更多还原
