    Synthesis and solution properties of some trans-cyanoacidotetraamminechromium(III) complexes
    摘要:
    The trans-[Cr(NH3)4(CN)X]+ ions, where X = NCS, F and Cl, have been prepared by reaction in methanol suspension of either trans-[Cr(NH3)4(H2O)(CN)]2+ with NCS- and F-, or trans-[Cr(NH3)4(Me2SO)Cl]2+ with CN-. Their perchlorate salts have been characterized by analysis, ion-exchange, conductance, absorption spectra, phosphorescence in room-temperature solution and aqueous chemistry. The solvent dependence of the ligand-field spectrum for X = F is ascribed to hydrogen bonding that affects the Cr-F interaction. Both pi(X) --> e(g)*(Cr) and t2g(Cr) --> pi*(CN) charge-transfer transitions are observed, consistent with the pi-donor and pi-acceptor nature of the two axial ligands. All these complexes undergo acid-catalysed CN- aquation. When X = Cl this competes with pH-independent loss of X. The aquation products, fully stereoretentive, confirm the trans isomerism of the new species. The anation and aquation behaviours reveal trans effects of the CN- ligand.

    2 ± 0.5 kcal mol–1 and ΔS‡=–13.5 ± 1.7 cal K–1 mol–1. Aquation of [Cr(NH3)5F]2+ yields [Cr(NH3)5(H2O)]3+(k2) and [Cr(NH3)4(H2O)F]2+(k3) with the latter predominating over the conditions [H+]= 0.01–1.00M investigated. From product analyses and kinetic studies at different [H+] rate constants have been obtained at 50 °C. I = 1.00M(LiClO4). Aquation of fluoride is [H+]-dependent,k2=a+b[H+] with a= 2.1

  • The Aluminium(III) Ion-assisted Aquation of the Pentaammine fluorochromium(III) Ion

    The aquation of the pentaamminefluorochromium(III) complex was found to be assisted by the aluminium ion. The observed pseudo-first-order rate constant, kobsd, can be written approximately as: kobsd=kAl[Al3+] (kAl=7.5×10−4 dm3 mol−1 s−1 at 35 °C, pH 3.0, I=2.0 mol dm−3). The rate constant decreased with an increase in the hydrogen-ion concentration, and this hydrogen-ion dependence was explained by
    发现离子有助于五 (III) 络合物的合。观察到的伪一级速率常数 kobsd 可以近似写为: kobsd=kAl[Al3+] (kAl=7.5×10−4 dm3 mol−1 s−1 at 35 °C, pH 3.0, I=2.0 mol dm-3)。速率常数随着离子浓度的增加而降低,这种离子依赖性可以通过假设离子对 CrF(NH3)52+ 的攻击被配体的质子化阻止来解释。对实验结果的分析给出了质子化常数的对数为 3.0±0.1。ClO4- 和 Co(CN)63- 对反应速率的影响通过考虑阴离子和反应阳离子之间离子对的形成来解释。
