本文用中子衍射数据确定了巴丙顿石的晶体结构。晶格常数为a=7.497（1），B=12.225（1），c=6.710（1）。a = 86.1S（1），r = 93.90（1），r = 112.27（0）（室温）。假设PI的空间群对称性，结构被细化。利用中子衍射中原子散射长度的差异确定了Mn和Mg在Fe（1）位和Al在Fe（2）位的阳离子分布。确定了氢原子的准确位置。
The crystal structure of babingtonite was determined from neutron .diffraction data at SOK. The lattice constants are a=7.497(l), b=12.225(1), c=6.710(1) A. a = 86.lS(1), ~ = 93.90(1) and r = 112.27(00 (at room temperature). The structure was refined assuming the space group symmetry of PI. The cation distributions of Mn and Mg in Fe(l) site and AI in Fe(2) site were confirmed by applying the differences of the scattering lengths of the atoms in neutron diffraction. The accurate positions of the hydrogen atoms were determined.
