Integrated X-ray crystallography, optical and computational methods in studies of structure and luminescence of new synthesized complexes of lanthanides with ligands derived from 2,6-diformylpyridine
(2011-03-24)
The reaction of 2,6-diformylpyridine-bis(benzoylhydrazone) [dfpbbh] and 2,6-diformylpyridine-bis(4-phenylsemicarbazone) [dfpbpsc] with lanthanides salts yielded the new chelates complexes [Eu(dfpbpsc-H +) 2]NO 3 (1), ...
Synthesis, characterization and crystal structure of racemic vanadyl and uranyl salen-type complexes
(2021-03-15)
Synthesis, characterization and crystal structure for racemic ONNO Schiff base ligand 3-OMe-t-salcn (trans-N,N’-bis(3-methoxysalicylidene)-1,2-cyclohexanediamine) and its vanadyl and uranyl complexes are reported. Both ...

Heteroleptic complexes of antifungal drugs with the silver ion
(John Wiley & Sons Ltd, 2016-11)
In spite of a large number of antibiotics and chemotherapeutics available for medical use, the emergence of old and new antibiotic resistance in the last decades revealed a substantial medical need for new classes of ...
From almost (para)-complex structures to affine structures on Lie groups
(Springer, 2018-01)
Let G= H⋉ K denote a semidirect product Lie group with Lie algebra g= h⊕ k, where k is an ideal and h is a subalgebra of the same dimension as k. There exist some natural split isomorphisms S with S2= ± Id on g: given any ...

Observation of stable 17 e iron(III) cyclopentadienyl radical complexes
(Sociedad Chilena de Quimica, 1999)
The EPR spectra of a series of mononuclear complexes [CpFe(dppe)SR]PF6 R = C6H5 (1), C3H7 (2), p-C6H4Br (3) and the binuclear [CpFe(dppe)-S-CH2CH2-S-CpFe(dppe)](PF6) 2 (4) were measured. All the paramagnetic complexes ...
Electrochemical modified electrodes based on metal-salen complexes
(Taylor & Francis Inc, 2007-01-01)
A general view of the electroanalytical applications of metal-salen complexes is discussed in this review. The family of Schiff bases derived from ethylenediamine and ortho-phenolic aldehydes (N,N'-ethylenebis(salicylideneiminato) ...
