摘要
合成了标题化合物[n-Bu4N]+[FeCl4]-,并通过元素分析和X-射线单晶衍射对其结构进行了表征。晶体属于正交晶系,空间群Pnna,晶胞参数为:a=1.851 0(4)nm,b=1.155 3(2)nm,c=1.144 2(2)nm,V=2.446 8(8)nm3,Z=8,Dc=1.195 g.cm-3,F(000)=932,μ=1.051 mm-1。化合物由一个独立的[FeCl4]-阴离子和一个独立的[n-Bu4N]+阳离子组成。在[FeCl4]-阴离子中,中心的铁原子与4个氯离子配位,形成一个扭曲的四面体构型,Fe Cl键键长分别为0.212 2(14)nm和0.218 07(17)nm。在[n-Bu4N]+阳离子中,氮原子同样处于一个扭曲的四面体构型。在固体状态下,独立的[FeCl4]-阴离子和[n-Bu4N]+阳离子通过弱的C H…Cl分子间相互作用力使晶体结构得以稳定。
The title compound, [n-Bu4N]^+ [FeCl4]^- was prepared and characterized by elemental analysis and X-ray crystallography. It crystallizes in the orthorhomhic system, space group Pnna, a=1. 851 0(4) nm,b=1. 155 3(2) nm, c=1. 144 2(2) nm, V =2.446 8(8) nm^3, Z=8, Dc=1. 195 g. cm^-3, F(000):932, μ=1.051 mm^-1. The crystal structure consists of one independent [FeCl4]^-anion and one independent [n-Bu4N]^+cation. In [FeCl4]^-anion, the central Fe atom adopts distorted tetrahedral geometry with four Cl atoms, and Fe-Cl bond distances are 0. 212 2 (14) nm and 0. 218 07(17) nm respectively. In [n-Bu4N]^+ cation, N atom also adopts a slightly distorted tetrahedral geometry. In the solid state, the C-H…Cl interactions link [FeCl4]^- anions and [n-Bu4N]^+ cations which stabilize the structure.
