The ambidentate nitrite ion, NO2−, is a biologically relevant species that can be coordinated to transition metals via the nitrogen or oxygen atom. Most of its physiological effects involve metalloproteins so it is important ...

The Fourier transform infrared and Raman spectra of the complexes hydrotris(pyrazolyl)borato rhenium tricarbonyl [TpRe(CO)3] and hydrotris(3,5-dimethylpyrazolyl)borato rhenium tricarbonyl [Tp*Re(CO)3] and their ligand salts ...

© 2017 Elsevier Inc. American Trypanosomiasis is a chronic infection discovered and described in 1909 by the Brazilian scientist Carlos Chagas. It is caused by the protozoan parasite Trypanosoma cruzi. Although it affects ...

Photochemical and photophysical properties of fac-[Re(CO)(3)(Clphen)(trans-L)](+) complexes, Clphen = 5-chloro-1,10-phenathroline and L = 1,2-bis(4-pyridyl)ethylene, bpe, or 4-styrylpyridine, stpy, were investigated to ...

Two β-carboline rhenium(I) complexes, fac-[Re(CO)3(dppz)(nHo)]O3SCF3 and fac-[Re(CO)3(nHo)2Cl] where dppz=dipyrido[3, 2-a:2′,3′-c] phenazine and nHo=9H-pyrido[3, 4-b]indole (norharmane), have been synthesized. These complexes ...

In previous work we proposed that polypyridylrhenium(I)tricarbonyl complexes coordinated to ion nitrite through its N-atom in CH2Cl2 solution could give nitrosyl complexes by electrochemical oxidation. In this work, we ...

The UV–Vis absorption spectrum of the rhenium(I) tricarbonyl complex [(NH2-phen)Re(CO)3Br] (ReNN-NH2Br, a deep-orange solid) in solution shows three bands located at 300, 370 and 445 nm. TD-DFT calculations and spectroscopic ...

In this work, we describe the photoisomerization of facial rhenium(I) tricarbonyl complexes bearing P,Nbidentate pyridyl/phosphine ligands with different chelating rings and anions: RePNBr, RePNTfO, and RePNNBr, which ...
