本文介绍利用一步法反应,分别合成出新的Fe_3S_3原子簇化合物[Et_4N]_3[Fe_3(p-CH_3PhS)_3Cl_3Br_3](1)和[Et_4N]_3[Fe_3(P-CH_3PhS)_3Cl_6](2)。X射线晶体结构测定表明,化合物1和2的阴离子骨架均为3Fe、3S交叉排列的六无环,略呈船型结构。1和2均属三斜晶系,空间群均为P1。1的晶胞参数:a= 12.301(2),b=13.780(4),c=19.097(2)A,α=101.39(2),β=101.92(1),γ=196.15(2)°,Z=2.2的晶胞参数:a=12.226(4),b=15.323(3),c=17.012(2)A,α=70·72(1),β=88.65(5),γ=72.51(2)°,Z=2。本文还讨论了该反应的立体化学和机理。
This paper describes the synthesis of new Fe 3 S 3 cluster compounds [Fe_3 (p_CH_3PhS) _3Cl_3Br_3] (1) and [Et_4N] _3 [Fe_3 (P_CH_3PhS) _3Cl_6] (2) by one-step reaction. X-ray crystal structure determination shows that the anion skeletons of compounds 1 and 2 are 3Fe, 3S cross arrangement of six no-ring, slightly ship structure. 1 and 2 belong to the triclinic system. The space group is the unit cell parameter of P1.1: a = 12.301 (2), b = 13.780 (4), c = 19.097 (2) A, , a = 12.226 (4), b = 15.323 (3), c = 17.012 (2) A, α = 70 · 72 (1), β = 88.65 (5), γ = 72.51 (2) °, Z = 2. This article also discusses the stereochemistry and mechanism of the reaction.
