Metal complex dyes of nickel with schiff bases

Dyes and Pigments, 1994
Nickel complexes with Schiff bases 2-(2-pyridylmethyleneamino)phenol (PMAP) and 2-(2-quinolylmethyleneamino)phenol (QMAP) were prepared and the composition of the crystalline complexes was determined by elemental analyses, solubilita, UV/VIS, IR and mass spectrometry. It was found that, for the Ni-PMAP complex , two ligands were bonded to one metal ion,

Schiff base complexes that form sandwich compounds

Journal of Molecular Modeling, 2018
In this article, we explore the capacity of formed Schiff base complexes to trap metal atoms or ions, using their aromatic ends. The intrinsic geometry of each complex defines the process of substitution. Two cases were studied; one involving a trans Schiff base complex and the other considering how a salen ligand, with nickel systems traps chromium ...

Schiff-base complexes of ruthenium(II)

Journal of the Chemical Society, Dalton Transactions, 1978
The interaction of dichlorotris(triphenylphosphine)ruthenium(II) with the sodium salts of various Schiff bases leads to complexes of the type trans-RuL(PPh3)2 for the quadridentate bifunctional ligands and RuL2(PPh3)2 for the bifunctional ligands.Interaction of the chloro-carbonyls, {Ru(CO)2Cl2}n or {Ru(CO)3Cl2}3, with the sodium salt of NN ...

A Uranium-Based Isothiosemicarbazone Schiff Base Complex

2016
A uranium(VI) complex UO2(L-Sal)EtOH has been synthesized by template reaction of 2-hydroxyacetophenone S-pentyl isothiosemicarbazone .hydrogen bromide (H2L), and salicylaldehyde (Sal) in the presence of uranium acetate salt. The complex was characterized by elemental analyses, IR, mass, UV–Vis, and X-ray diffraction methods.
