Mixed complexes of cobalt(III) with phenanthroline and galactose or arabinose
Mixed complexes of bis-phenanthroline cobalt(III) and α-D-galactose or β-D- or L-arabinose are identified in aqueous solution from their 1H NMR and circular dichroism (CD) spectra. Galactose forms only the Δ-complex, but ...

Análise complexa e aplicações
(Universidade Estadual Paulista (UNESP), 2018-04-20)
O objetivo principal deste trabalho é desenvolver um estudo introdutório, porém detalhado, sobre Análise Complexa e algumas de suas aplicações. Apresentamos o corpo dos números complexos, exploramos as funções complexas ...
Synthesis and characterization of ruthenium(II) complexes incorporating 4-phenyl-terpyridine and triphenylphosphine
(Taylor & Francis, 2015)
The syntheses of two new series of ruthenium(II) complexes incorporating substituted 4-phenylterpyridine, triphenylphosphine, and chloride (A Series) or hydride (B Series) are reported. In both series 4-phenyl-terpyridine ...
Measurement of metal-complexing ability of polyfunctional macromolecules: a discussion of the relationship between the metal-complexing properties of extracted soil organic matter and soil genesis and plant nutrition
(The Williams & Wilkins Co., 1975)
Characterization of the metal-complexing ability of polyfunctional macromolecules through the determination of stability constants of their metalic complexes is discussed along with the validity of ascribing a relationship ...
Star clusters in independence complexes of graphs
(Academic Press Inc Elsevier Science, 2013-03)
We introduce the notion of star cluster of a simplex in a simplicial complex. This concept provides a general tool to study the topology of independence complexes of graphs. We use star clusters to answer a question arisen ...
The Wilkinson Complex as a heterogeneous catalyst in the partial hydrogenation of 1-heptyne. regeneration of the complex
(Sociedade Brasileira de Química, 2016-06)
The Wilkinson complex was tested as a catalyst in the partial hydrogenation of 1-heptyne, a medium chain alkyne, at a temperature of T = 303 K and hydrogen pressure PH2 = 150 kPa. The tests were performed in homogeneous ...
