  • Sulfate as a ligand in ruthenium(II) and (III) ammines
    作者:Hildo Antonio dos Santos Silva、Bruce R McGarvey、Regina Helena de Almeida Santos、Mauro Bertotti、Vânia Mori、Douglas Wagner Franco
    DOI:10.1139/v01-036
    日期:2001.5.1

    The trans-[RuSO4(NH3)4(L)]Cl complexes, (L = nicotinamide (nia), L-histidine (L-hist), 4-picoline (4-pic), 4-chloropyridine (4-Clpy), isonicotinamide (isn), pyrazine (pyz), 4-aminopyridine (4-NH2py), 4-cyanopyridine (4-CNpy), pyridine (py), imidazole (Him), and water (H2O)), were characterized by elemental analysis cyclic voltammetry, UV-vis, IR, and electron paramagnetic resonance spectroscopies. From the four ν (SO4) observed only ν3 and ν4 split in two bands each for the sulfate unidentate coordination. The values of Δ/ξ parameters, extracted from g values, allow us to write the following order of increasing π-donation ability: pyz < (py, 4-CNpy, 4-Clpy. 4-pic, isn, nia) < Him < L-hist < 4-NH2py. The intense absorption in the 317-347 nm (ε ~ 2.3-5.6 × 103 M-1 cm-1) region was tentatively assigned to sulfate-to-metal charge transfer (LMCT) and the absorption in the range of 230-270 nm (ε ~ 2 - 6 × 103 M-1 cm-1) assigned to an internal (IL) π-π* transition in the heterocyclic ligands. The rate for the sulfate aquation in trans-[RuSO4(NH3)4L]0 complexes was evaluated through chronopotentiometric measurements and are in the 2.6 s-1 (chloropyridine) to 20 s-1 (pyrazine) range. The SO4 is aquated in trans-[RuIIISO4(NH3)4(4-pic)]Cl at the specific rate constant of (1.4 ± 0.4) × 10-5 s-1, which is very much slower than in trans-[RuIISO4(NH3)4(4-pic)] (5.4 s-1). The X-ray crystal structure data show that the Ru-Cl (2.3444(9) Å) and Ru-NH3 (2.100(2) Å) mean distances in trans-[RuCl(NH3)4(4-pic)]Cl2·H2O are similar to the ones observed in other tetraammineruthenium(III) complexes.Key words: ruthenium, sulfate, ammines.

    转-[RuSO₄(NH₃)₄(L)]Cl络合物(L = 烟酰胺(nia),L-组氨酸(L-组),4-吡啶(4-pic),4-氯吡啶(4-Clpy),异烟酰胺(isn),吡啶(pyz),4-氨基吡啶(4-NH₂py),4-氰基吡啶(4-CNpy),吡啶(py),咪唑(Him)和(H₂O))通过元素分析、循环伏安法、紫外-可见光谱、红外光谱和电子顺磁共振光谱进行了表征。从观察到的四个ν(SO₄²⁻)中,只有ν₃和ν₄在硫酸盐单齿配位中分裂成两个带。从g值中提取的Δ/ξ参数值使我们能够写出以下 π-给体能力增加顺序:pyz < (py, 4-CNpy, 4-Clpy. 4-pic, isn, nia) < Him < L-组氨酸 < 4-NH₂py。在317-347 nm(ε ~ 2.3-5.6 × 10³ M⁻¹ cm⁻¹)区域的强吸收被暂时归属为硫酸盐到金属的电荷转移(LMCT),在230-270 nm范围内的吸收(ε ~ 2-6 × 10³ M⁻¹ cm⁻¹)被归属为杂环配体中的内部(IL)π-π*跃迁。通过电位时间法测量评估了转-[RuSO₄(NH₃)₄L]⁰络合物中硫酸盐水合作用的速率,范围为2.6 s⁻¹(氯吡啶)到20 s⁻¹(吡啶)。SO₄²⁻在转-[Ru⁢III⁢SO₄(NH₃)₄(4-pic)]Cl中以特定速率常数(1.4 ± 0.4)× 10⁻⁵ s⁻¹进行水合,这比在转-[Ru⁡II⁢SO₄(NH₃)₄(4-pic)](5.4 s⁻¹)中慢得多。X射线晶体结构数据显示,转-[RuCl(NH₃)₄(4-pic)]Cl₂·H₂O中的Ru-Cl(2.3444(9) Å)和Ru-NH₃(2.100(2) Å)的平均距离与其他四胺合铑(III)络合物中观察到的距离相似。关键词:钌,硫酸盐,胺。
