Hydrogen-bonded complexes between chloral hydrate and halide ions in aqueous solution.
نویسندگان
چکیده
The hydrogen-bonded interactions of chloral hydrate and halide ions have been investigated conductometrically at 25.00 degrees C in aqueous solutions. In spite of the strong competing effect of water, the 1:1 associates have relatively high stability constants, in the order of chloride greater than bromide greater than fluoride approximately equal to iodide. The rather low stability of the fluoride:chloral hydrate associate can be explained by the strong hydration of the small fluoride ion. Although the 1:1 association dominates, other stoichiometries cannot be excluded; the cations and the ionic strength seem to have no effect.

Spectrophotometric Study of Complex Formations between Alprazolam and Some Transition Metal Ions in Non Aqueous Solution
In this study, the complexation reaction between Alprazolam (ALP) and metal ions (Zn2+, Ni2+, Cu2+ and Co2+) was investigated by using spectrophotometry in ethanol solvent. The stoichiometry of M+/ALP complexes was calculated by applying the Job, molar ratio and Continuous Changes methods and the relevant diagrams were plotted for each metal ions in each method. The results show that the obtain...
متن کاملModelling the effects of salt solutions on the hydration of calcium ions.
Classical molecular dynamics simulations of several aqueous alkali halide salt solutions have been used to determine the effect of electrolytes on the structure of water and the hydration properties of calcium ions. Compared with the simulations of Ca(2+) ions in pure liquid water, the frequency of water exchange in the first hydration shell of calcium, which is a fundamental process in control...

متن کاملComparison effect of pentobarbital sodium with chloral hydrate anesthesia on post-ischemic damage in an experimental model of focal cerebral ischemia
Introduction: Anesthetic agents, blood pressure, arterial pH and blood gases have found to influence on the pathophysiology of experimental stroke. Despite, there are very few comparative studies about effects of anesthetic agents in animal model of cerebral ischemia. Therefore, in this study, we investigated the effects of chloral hydrate and pentobarbital anesthesia, as comparative study, on...
متن کاملCrystal structures of fac-tricarbonylchlorido(6,6′-dihydroxy-2,2′-bipyridine)rhenium(I) tetrahydrofuran monosolvate and fac-bromidotricarbonyl(6,6′-dihydroxy-2,2′-bipyridine)manganese(I) tetrahydrofuran monosolvate
The structures of two facially coordinated Group VII metal complexes, fac-[ReCl(C10H8N2O2)(CO)3]·C4H8O (I·THF) and fac-[MnBr(C10H8N2O2)(CO)3]·C4H8O (II·THF), are reported. In both complexes, the metal ion is coordinated by three carbonyl ligands, a halide ligand, and a 6,6'-dihy-droxy-2,2'-bi-pyridine ligand in a distorted octa-hedral geometry. Both complexes co-crystallize with a non-coordinat...
