The structure of the coordination compound [Fe(teec)6](BF4)2, hexa[1-(2-chloroethyl)tetrazole]iron(II) di(borotetrafluoride), has been determined using the grid-search techniques of the program suite MRIA. A Guinier-camera data set was used to determine the unit cell, the space group and to position the initial model. A high-resolution synchrotron powder data set was used to position a more detailed model using torsion-angle variation and to refine the structure leading to Rp = 0.0689, Rw = 0.0805 and GoF = 1.38. The crystal structure at room temperature shows the existence of two symmetry-equivalent iron(II) ions in the high-spin state.
利用 MRIA 程序套件的网格搜索技术,确定了六[1-(2-氯乙基)四氮唑]铁(II)二(氟化硼)配位化合物 [Fe(teec)6](BF4)2 的结构。使用 Guinier 相机数据集确定了单胞、空间群和初始模型的位置。高分辨率同步辐射粉末数据集用于利用扭转角变化定位更详细的模型,并完善结构,最终得出 Rp = 0.0689、Rw = 0.0805 和 GoF = 1.38。室温下的晶体结构显示,在高自旋状态下存在两个对称等价的铁(II)离子。
