Venegas Yazigi, Diego; Campos Vallette, Marcelo; Lever, A. B.P.; Costamagna, J.; Latorre, Ramón; Hernández G., W. (2003)It has been shown that innocent ligands always contribute with a similar electron density to a metal centre in a complex regardless of which other innocent ligands are bonded to the same centre, while non-innocent ligands ...

Isaacs, M.; Aguirre, M. J.; Toro Labbé, Alejandro; Costamagna, J.; Páez, M.; Zagal Moya, José H. (Elsevier Ltd, 1998)Cobalt phthalocyanine (CoPc) and cobalt naphthalocyanine (CoNPc) exhibit different redox and electronic properties. Redox processes on CoPc are more reversible than on CoNPc. The pH dependence of those processes is also ...

Costamagna, J.; Ferraudi, G.; Matsuhiro, B.; Campos Vallette, Marcelo; Canales, J.; Villagrán, M.; Vargas, J.; Aguirre, M. J. (Elsevier, 2000)Recent literature results on inorganic models related to metalloenzymes which transport electrons or activate small molecules are discussed in this review. The molecular systems are essentially restricted to macrocyclic ...

Granifo, J.; Costamagna, J.; Garrao, A.; Pieber, M. (1980)We describe a procedure for the preparation of various metal thiourea complexes of the type [M(CO)5L] in which M Cr or W and L TU (thiourea), TMTU (tetramethylthiourea), DptTU (NN′-di-p-totyl thiourea); DtBTU = (NN′-di-t-butyl ...

Campos Vallette, Marcelo; Figueroa, K. A.; Latorre, R.; Manriquez, V.; Díaz Fleming, Guillermo; Costamagna, J.; Otero, M. (1992)The crystal and molecular structure of bis-(N-phenyl-1-hydroxy-2-naphthylaldiminate) nickel(II) (1) have been determined by x-ray crystallography. The compound crystallizes in the triclinic space group P1, No. 2 with one ...

Díaz Fleming, Guillermo; Campos Vallette, Marcelo; Saavedra, M. S.; Clavijo Campos, Ernesto; Canales, J. C.; Costamagna, J.; Vargas, J. (Elsevier, 2002)A complete assignment of the infrared spectra of the title macrocycles was carried out on the basis of well-documented references and a normal coordinate analysis based on a simplified molecular model. The structure of the ...

Campos Vallette, Marcelo; Figueroa, K.; Latorre, Ramón; Díaz Fleming, Guillermo; Costamagna, J.; Canales, J. C.; Rey-Lafon, M.; Derouault, J. (1993)The infrared spectra of seven bis(N-phenyl-substituted hydroxynaphthylaldiminate) complexes of Cu(II) were scanned from 4000 to 100 cm-1. Particular emphasis is given to the low-energy region. The assignment of the chelate ...

Olave, C. R.; Carrasco, E. A. F.; Campos Vallette, Marcelo; Saavedra, M. S.; Clavijo, R. E.; Figueroa, W.; Díaz Fleming, Guillermo; Sánchez Cortés, S.; Domingo, C.; Costamagna, J.; Ríos, A. (Elsevier, 2002)The FT-IR and Raman spectra in the solid state, the reflection-absorption IR spectra (RAIRS) and the surface enhanced IR (SEIR) and surface enhanced Raman spectra (SERS) of the Ni(II) (trans-7,14-dimethyl-5,12,-diphenyl- ...
