    • Bonding in tetrahedral Cu4(μ3-X)4L 4 Copper(I) clusters: A DFT investigation 

      Vega, Andrés; Saillard, Jean Yves (2004)
      DFT calculations on Cu4(μ3-X)4L 4 (X = H, CH3, CCH, F, Cl, Br, I; L = NH3, PH3) indicate that, regardless of its nature, X- acts essentially as a two-electron σ-type ligand and that the covalent part of the Cu⋯Cu bonding ...
    • Iron-iron interaction through an ethanedithiolate ligand: A magnetic and theoretical study 

      Costuas, Karine; Valenzuela, María Luisa; Vega, Andrés; Moreno, Yanko; Pea, Octavio; Spodine Spiridonova, Evgenia; Saillard, Jean Yves; Díaz, Carlos (2002)
      The compound ([CpFe(dppe)]2[μ-SCH2CH2S-S,S′]) (PF6)2 ([1][PF6]2) has been synthesized and its magnetic properties have been investigated by susceptometer quantum interface device (SQUID) measurements in the temperature ...
    • Magnetic properties of dinuclear copper(II) complexes with a N6 pyridazine-derived ligand 

      Spodine Spiridonova, Evgenia; Atria Salas, Ana María; Manzur Saffie, Jorge; García, Ana María; Garland, María Teresa; Hocquet, Alexandre; Sanhueza, Eduardo; Baggio, Ricardo; Peña, Octavio; Saillard, Jean Yves (1997)
      A new hexadentate ligand 3,6-bis[(6-methyl-2-pyridyl)(2-pyridyl)methyl]pyridazine (mbdpdz) was prepared by a condensation reaction of 3,6-dichloropyridazine and (6-methyl-2-pyridyl)(2-pyridyl)methyllithium, and the following ...
    • A Novel Copper Cobalt Inorganometallic Cluster. Synthesis, Structure and Bonding Analysis of Cu3{í2-(CCHCo2(CO)6)}3 

      Vega, Andrés; Calvo Pérez, Víctor; Spodine Spiridonova, Evgenia; Zárate, Antonio; Fuenzalida Escobar, Víctor; Saillard, Jean-Yves (2002)
      The reaction of the organometallic carboxylic acid HOOCCCHCo2(CO)6 with copper(II) methoxide leads to a new inorganometallic cluster; Cu3{í2-(CCHCo2(CO)6)}3. This cluster has a triangular core of copper(I) centers ...
    • Structure and bonding in the hydrothermally synthesized copper(I) complex Cu4(μ2-Cl)4(BIPY)2 

      Moreno, Yanko; Spodine Spiridonova, Evgenia; Vega, Andrés; Saillard, Jean Yves (Elsevier S.A., 2003)
      The title compound corresponds to a molecular product of the hydrothermal reaction of CuCl2, Zn, and BIPY (BIPY=2,2′-bipyridine) in the presence of phosphoric acid. The structure of the neutral complex Cu 4(μ2-Cl)4(BIPY)2 ...
