摘要

摘要报道了三种五氰铁酸盐(III)配合物[Fe(CN)5L]3-与L = 4-氰吡啶、4,4′-联吡啶或4-t-丁基吡啶在一系列水溶液中取代配体的速率常数。这些盐包括钾、锂和钙的氯化物和溴化物，以及四烷基溴化铵，浓度范围在0.50和2.00 mol dm-3之间。将所观察到的趋势与选择的其他无机反应的趋势进行比较。

Salt Effects on Reactivity for Substitution Reactions of Pentacyanoferrate(II) Complexes

Abstract Rate constants are reported for ligand replacement in three pentacyanoferrate(III) complexes [Fe(CN)5L]3- with L = 4-cyanopyridine, 4,4'-bipyridyl, or 4-t-butyl-pyridine, in a range of aqueous salt solutions. These salts include chlorides and bromides of potassium, lithium, and calcium, and tetra-alkyl-ammonium bromides, at concentrations within the range 0.50 and 2.00 mol dm-3. The observed trends are compared with those for a selection of other inorganic reactions.
