    An Spectroscopic Investigation of Complex Formation in nickel sulphate-aliphatic amine system (1968)
    New York, NY : Wiley-Blackwell

    Notes: Visible absorption spectra of Nickel (II) sulphate and various aliphatic amines were analysed, in order to extract information regarding each of amine Nickel (II) complex. The presence of six different complexes i.e., mono, di, tri, tetra, penta and hexamines have been indicated by the shift of absorption maxima for these. The energy changes of complexes due to exchange of water ligands with amines have been calculated and an interpretation is offered for this shift in the observed position of absorption maxima.

    Preparation, Absorption Spectra and Electronic Configuration of some amino complexes of nickel (II) acetate (1968)

    Notes: Three hexaco-ordinated complexes of nickel (II) acetate with ammonia, ethylenediamine and propylenediamine have been prepared. Conductivity measurements indicate the complexes to be non-electrolytes. Molecular weight measurements confirm this. The visible absorption spectrophotometric measurements show a number of bands corresponding to the various permitted transitions of the metal and a discussion of the structure in the light of these transitions is presented.

    Notes: Some complexes of cerium (IV) sulphate with ammonia and primary aliphatic amines have been prepared. The molecular formulae on the basis of analysis turn out to be Ce(SO4)2 · 4 amine. The complexes behave as electrolytes. The absorption spectra have been recorded and an interpretation is offered for possible transitions.Lanthanides, and cerium in particular are receiving special attention these days. A number of complexes of latter with various ligands and anions have been reported1-5). In the present paper some complexes of cerium (IV) sulphate with ammonia, methyl, ethyl, propyl and butylamine are being presented.

    Notes: Some molecular addition compounds of cobalt (II) oxalate with primary aliphatic amines have been prepared. The general molecular formula on the basis of analysis of constituent elements turn out to be CoC2O4 · RNH2. The formation of compounds is independent of the excess amine concentration. The compounds behave as electrolytes. The molecular weight measurements and VAN'T HOFF factor “i” also confirm this fact.

    Investigations on some amino complexes of copper (II) benzoate. Preparation, Preliminary Investigations and Absorption Spectra (1968)
    New York, NY : Wiley-Blackwell

    Notes: Co-ordination complexes between Copper (II) benzoate and ammonia, some diphatic and aromatic amines and a few diamines have been prepared. The molecular formulae on the basis of percentages of constituent elements are Cu(benzoate)2(amines)2 and Cu(benzoate)2-(amine). Conductivity measurements in formamide, nitrobenzene and water indicate the complexes to be non-electrolytes and hence it is suggested that the benzoate ions are also co-ordinated. Molecular weight measurements in the same solvents confirm this. Visible absorption measurements show a single band in the 600-900 mμ region of the spectrum.

    Description / Table of Contents: Es wurden gelbe Komplexe des Nickel(II)-chromats mit Ammoniak, Äthylendiamin und Propylendiamin dargestellt. Leitfähigkeitsmessungen zeigen, daß sie in wäßriger Lösung in zwei Ionen dissoziieren. Ihre magnetische Suszeptibilität und die Absorptionsspektren im sichtbaren Bereich deuten auf eine quadratisch-planare Koordination des Nickels hin.
    Notes: Tetraco-ordinated complexes of nickel(II) chromate with ammonia, ethylenediamine and propylenediamine have been prepared. Conductivity measurements in water have shown the complexes dissociating in two ions. Magnetic susceptibility and visible absorption spectra suggest square planar configurations.
