合成了一个新的离子型化合物[Fe(CN)6.(PhCH2NC9H7)4.KCl.H2O].5H2O。经红外光谱、元素分析及X-射线衍射对其结构进行了表征,并采用循环伏安法研究了它的电化学性质。化合物晶体属三斜晶系,P1空间群,晶胞参数:a=11.068(7),b=11.139(7),c=14.837(9),α=76.724(8)°,β=81.499(8)°,γ=68.537(7)°,V=1652.9(17)3,Mr=1275.74,Z=1,Dc=1.282Mg.m-3,F(000)=668,吸收系数μ=0.391mm-1,最终偏离因子R1=0.0623,wR2=0.1582。化合物的基本单元是由4个(PhCH2N+C9H7)离子、一个[Fe(CN)6]4-离子、一个水合氯化钾分子及5个水分子组成。由结构分析结果可知,[Fe(CN)6]4-通过氢键相互联接,而(PhCH2N+C9H7)和[Fe(CN)6]4-离子是靠静电引力结合在一起的。
A new ionic compound [Fe (CN) 6 (PhCH2NC9H7) 4.KCl.H2O] .5H2O was synthesized. Its structure was characterized by FTIR, elemental analysis and X-ray diffraction, and its electrochemical properties were studied by cyclic voltammetry. The crystal of the compound belongs to the triclinic system with space group P1 and unit cell parameters: a = 11.068 (7) , b = 11.139 7, c = 14.837 9, α = 76.724 8, β = 81.499 (8) °, γ = 68.537 (7) °, V = 1652.9 (17) 3, Mr = 1275.74, Z = 1, Dc = 1.282Mg.m- 3, F (000) = 668, absorption coefficient μ = 0.391mm-1, the final deviation factor R1 = 0.0623, wR2 = 0.1582. The basic unit of the compound consists of four (PhCH2N + C9H7) ions, one [Fe (CN) 6] 4-ion, one hydrated potassium chloride molecule and five water molecules. From the results of structural analysis, [Fe (CN) 6] 4- are linked by hydrogen bonds and the (PhCH2N + C9H7) and [Fe (CN) 6] 4- ions are bound by electrostatic attraction.
