This book was released on 1978 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrated cobalt(II) and nickel(II) trifluoromethanesulfonates have been prepared by a previously reported procedure, and have been characterized for the first time as [Co(H2O)6] (CF3SO3)2H2O and [Ni(H2O)6] (CF3SO3)2. These formulations are based on analyses, near-infrared spectra, and on measurements of the ligand field electronic spectra and the magnetic susceptibilities. The metal ions are high-spin and octahedrally coordinated in both compounds. Methods have been developed for the preparation of the pure anhydrous cobalt(II) and the previously unknown nickel(II) trifluoromethanesulfonates from the hydrates. By determination of the d-d spectra and the magnetic moments, these are found to contain high-spin octahedrally coordinated metal cations, and therefore contain coordinated trifluoromethanesulfonate anions. The near-infrared spectral absorptions of these anions have been observed. The magnetic moment reported by previous workers for anhydrous cobalt(II) trifluoromethanesulfonate corresponds to the value found in this work for the hydrate. By vacuum line methods, pressure-composition data have been obtained for the triethylamine-cobalt(II) and nickel(II) trifluoromethanesulfonate systems. Breaks in the 25° isothermal phase diagrams show that very unstable adducts containing two molecules of triethylamine per metal ion are formed in each system. These could not be isolated. Various experimental methods for the preparation of quinuclidine complexes were investigated. The one found to be successful involved mixing, by Schlenk techniques, acetonitrile solutions of the anhydrous metal trifluoromethanesulfonate and of an excess of quinuclidine, evaporating the solvent, and removing the excess quinuclidine by sublimation. The solid complexes obtained in this way were characterized as [Co(QUIN)4] (CF3SO3)2 and [Ni(QUIN)2(CF3SO3)2] by their analyses, ligand field spectra, magnetic moments, and the near-infrared absorptions of the anions. As expected, quinuclidine is found to be a better ligand than its more sterically demanding analogue, triethylamine. The quinuclidine complexes of cobalt(II) and nickel(II) trifluoromethanesulfonates are much more stable. In the case of the cobalt complexes, the metal ion has a greater ligation number for quinuclidine than for triethylamine. In these solid salts and complexes, the trifluoromethanesulfonate ion shows a much greater tendency to coordinate than had been expected, based on a previous study using it in aqueous solution.

Available in PDF, EPUB and Kindle. Book excerpt: The rate constants for the formation and dis sociation of Ni(II) and Co(II) complexes with one, two and three glycine, diglycine, or imida zole molecules were determined by the temperature jump technique. The approximate time scale of the reactions studied ranged from 0.1 to 500 msec. The rate-determining step of the complex building reaction, following initial formation of an ion pair, is the dissociation of a water molecule from the inner hydration sphere of the metal ion. The measured rate constants can be normalized with respect to electrostatic and steric factors by dividing out the calculated ion-pair equilibrium constant. The rate constant of dissociation thus obtained is characteristic of a given metal ion, and, in nearly all the re actions studied, was 20 to 25 times greater for Co(II) than for Ni(II). The difference in acti vation energies corresponding to this rate ratio is of the order of magnitude predicted on the basis of crystal-field theories. For glycine, these normalized rate constants tend to increase in reactions involving the higher complexes, in dicating a loosening of the hydration shell due to the fact that the glycine is bound to the metal via the negatively charged carboxyl group. These rate constants are independent of the number of ligands bound if the bonding takes place via uncharged groups. (Author).

Book excerpt: Some nickel(II) and cobalt(II) salts have been found to react readily with 1,2-bis(mercapto)-o-carborane in the presence of stabilizing phosphorous ligands or the tetraethylammonium cation to yield square planar MS2P2 and MS4(2) complexes. Electronic spectra of the nickel complexes are discussed. (Author).
