“…The Cu 9 9 -Cu separation in the class of similar compounds correlates with the values of the coupling constants for the spin-spin interaction found by Jotham et al (1972) by magnetic measurements. The deviations of the copper atom from the plane of thc four oxygen atoms of the carboxyl groups also show systematic dependence.…”

Green, needle-shaped crystals of copper acetate mono-e-picoline, Cu(ac)2-(e-pic), crystallize in space group P21/c with cell dimensions a=7.675(4), b =20.008(6), c= 8.207(4)~, and fl = 115.99(3) ~ The crystal structure has been solved by the heavy-atom method and refined with the three-dimensional x-ray photographic data to an R factor of 9.2%. The structure consists of binuclear units Cu2(act4(~-pic)2. The Cu-Cu distance is 2.671 ,~. The bond length Cu-N (2 24 A) is significantly longer than the corresponding distance in analogous complexes.

“…1), as found for copper(II) acetate with a Cu…Cu distance of 2.607(8) A [7]. This structure has been postulated to give rise to the existence of a strong electronic and magnetic communication between the two unpaired electrons on the Cu(II) ion and allows for ready delocalization of the electrons [8][9].…”

“…Previous studies suggest a correlation between J and the electronegativity of the atom directly bonded to the carbon atom of the carboxylato group. [12,14,98] If one considers an average value for acetato, trifluoroacetato, and trichloroacetato bridges, this correlation seems to indicate that the more electronegative this atom, the weaker is the coupling. According to this trend, compounds with haloformiato bridges should be those with the weakest coupling.…”

Exchange Coupling in Carboxylato-Bridged Dinuclear Copper(II) Compounds: A Density Functional Study

et al. 2001

View full text Add to dashboard Cite

A computational study of the exchange coupling is presented for a selected sample of carboxylato-bridged dinuclear copper(II) compounds. Model calculations have been used to examine the influence of several factors on the coupling constants: a) the electron-withdrawing power of the bridging ligands; b) the nature of the axial ligands; c) the number of bridging carboxylato groups; d) some structural distortions frequently found in this family of compounds; and e) the coordination mode of the carboxylato bridge. Coupling constants calculated for some complete structures, as determined by X-ray diffraction, are in excellent agreement with experimental data, confirming the ability of the computational strategy used in this work to predict the coupling constant for compounds for which experimental data are not yet available.
