用氯化亚铁、苯硫酚钠及溴化四乙基铵在乙腈溶液中,经一步反应,得到两个同分异构的化合物α-[Et_4N]_3[Fe_3(PhS)_3Cl_3Br_3]1和β-[Et_4N]_3[Fe_3(PhS)_3Cl_3Br_3]2.X 射线晶体结构测定表明,1和2的阴离子骨架为3Fe、3S 交叉排列的六元环,前者为扭船型,后者为椅型.1属单斜晶系,空间群 C2/c,晶胞参数:a=24.569(4),b=13.504(2),c=18.348(3)■,β=110.78(1)°.Z=4,R=0.070.2属三方晶系,空间群 Pucl,晶胞参数:a=b=13.720(3),c=35.748(5)(■.Z=4,R=0.059.讨论了反应和结构特点.
Two isomeric compounds α - [Et_4N] _3 [Fe_3 (PhS) _3Cl_3Br_3] 1 were obtained by one step reaction with ferrous chloride, sodium thiophenolate and tetraethylammonium bromide in acetonitrile The crystal structure of X-ray crystallography shows that the anion skeletons of 1 and 2 are 6-membered rings with 3Fe and 3S crossings, the former being of the torsion type and the latter being of the chair type. 1 is a monoclinic with a space group of C2 / c, with unit cell parameters of a = 24.569 (4), b = 13.504 (2), c = 18.348 (3) , R = 0.070.2 belongs to the trigonal system, the space group Pucl, unit cell parameters: a = b = 13.720 (3), c = 35.748 (5) Features.
