    Solute-solvent interaction involving MX2Ln type complexes in mixed solvent media. I. Outer-sphere interactions of the NiCl2py4 complex in pyridine + diluent solutions (1985)
    Springer
    Journal of solution chemistry 14 (1985), S. 735-750 
    Details
    ISSN: 1572-8927
    Keywords: Dichlorotetrapyridine nickel (II) ; pyridine ; chloroform ; 1,1,2,2-tetrachloroethane ; aniline ; benzene ; chlorobenzene ; heats of solution ; enthalpies and entropies of transfer ; specific outer-sphere interactions of transition metal complexes ; solvent effect
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract The standard enthalpies and entropies of transfer from pyridine to pyridine+diluent mixtures of varying composition have been determined for the NiCl2py4 complex at 25°C using chloroform, 1,1,2,2-tetrachloroethane, aniline, benzene, and chlorobenzene as the diluents. Large negative enthalpies of transfer to solvent mixtures involving the protic diluents contrast with the small effects observed for the aprotic diluents. For the latter, the negative entropies of transfer agree with the assumption that pyridine molecules remain attached to the complex when the diluent is added to pyridine, indicating outer-sphere interaction of the amine with the complex. Solvent effects observed in the near infrared ligand-field spectrum of NiCl2py4 support the assumption of specific outer-sphere interactions with protic diluents. Additional information about these interactions is provided by the CTCT(t 2g→π*) metal-to-ligand band in the UV.

    Complexes of divalent ions in mixed solvent media. III. Outer-sphere interactions in amine + diluent solutions (1988)
    Springer
    Journal of solution chemistry 17 (1988), S. 371-382 
    Details
    ISSN: 1572-8927
    Keywords: Transition metal complexes ; non-aqueous solvents ; heats of solution ; thermodynamic functions of transfer ; outer-sphere interactions ; solvent effect
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract The standard enthalpies and (in part) free energies and entropies of transfer from amine (L) to amine + diluent (D) mixtures have been determined for MX2L2 complexes at 25°C using chloroform, 1,1,2,2,-tetrachloroethane (TCE), benzene, chlorobenzene, and ethyl acetate as diluents (M=Co and Zn; X=Cl and Br; L = pyridine, α-picoline, and γ-picoline). Thermodynamic functions of transfer indicate specific outer-sphere interactions of the complexes with amine and protic diluents (chloroform and TCE) and reveal solvent-solvent interactions of amine + protic diluent mixtures. The effects of the nature of X, L, and M of the MX2L2 complexes on their interaction with the components of the mixed solvent are discussed.

    Free energies of transfer of ZnCl2py2 and of related tetrahedral complexes from pyridine to other solvent media (1983)
    Springer
    Journal of solution chemistry 12 (1983), S. 529-546 
    Details
    ISSN: 1572-8927
    Keywords: Solubility ; free energies of transfer ; outer sphere interactions ; transition metal complexes ; pyridine ; diluents ; zinc chloride and bromide
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract The standard Gibbs free energies of transfer from pyridine to pyridine+diluent mixtures are reported for the ZnCl2py2 complex at 25°C. Their variations with varying mixed solvent composition agree with those expected for regular solutions when the diluents are polar and basic while marked deviations are observed for non-polar, inert diluents. For protic diluents the free energies of transfer of ZnCl2py2 exhibit maxima, indicating specific interaction of the complex with both solvent components in these systems. The free energies of transfer of ZnCl2py2 to the pure diluents plotted vs. the solubility parameter of the latter reveal separate Hildebrand correlations for inert and for basic solvents, with the free energies of transfer of the complex to the protic solvents deviating from both. Weak specific interactions of ZnCl2py2 with the basic solvents and stronger interactions with the protic solvents are inferred and further examined in the light of the free energy of transfer data for the related tetrahedral complexes ZnBr2py2, ZnCl2(α-pic)2, CoCl2(α-pic)2, and ZnBr2(α-pic)2.1H-NMR spectrum of the pyridine ligands of ZnCl2py2 confirm their involvement in weak hydrogen-bond formation with the basic solvents, while the downfield shift observed for the solvent chloroform is consistent with hydrogen bond formation of the latter with the chloro-ligands.

    ISSN: 1572-8927
    Keywords: Manganese, cobalt, nickel, zinc, magnesium and calcium perchlorate ; aqueous solutions ; infrared spectra ; isotopic dilution method ; deconvolution of spectra ; OD groups
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract Aqueous solutions of Mn(II), Co(II), Ni(II), and Zn(II) perchlorates, and for comparison, Mg(II) and Ca(II) perchlorates, have been studied by IR spectroscopy using HDO as an indicator. The investigations were carried out over the entire available concentration range of these salts. Computer deconvolution of the measured spectra demonstrates the effect of metal cations on the HDO molecules.

    Notes: Abstract The enthalpies and (in part) free energies and entropies of transfer from pyridine to pyridine + diluent mixtures have been determined for MnCl2py4, Mn(NCS)2py4, Co(NCS)2py4, Ni(NCS)2py4, and NiBr2py4 complexes at 25°C using chloroform or 1,1,2,2-tetrachloroethane (TCE) as diluents. The ΔH tr o data indicate specific outer-sphere interactions of the complexes with the diluents. The influence of the kind of anionic ligands and central metal ion of the complexes on their interaction with the diluents are discussed.
