dc.description.abstract [EN] The new bimetallic nickel(II) compound (PPh4)4[Ni2(2)]·6H2O (3), where H8[2] stands for N,N',N'',N'''-1,2,4,5-benzene-tetrayltetrakis(oxamic acid), has been synthesized and its crystal structure determined by single-crystal X-ray diffraction. The structure of 3 consists of [Ni2(n4:n4-2)]4- anions, tetraphenylphosphonium cations, and water molecules. Facile one-electron oxidation of the square-planar diamagnetic dinickel(II) complex [Ni2(n4:n4-2)]4- generates the metallo-radical species [Ni2(n4:n4-2·+)]3- with characteristic intra-ligand ¿cation radical transitions in the visible region (475-550 nm) as well as a typical quasi-isotropic EPR signal at g ¿ 2.0. es_ES

In the calculations, the metal ions and the ligand have been explicitly taken into account. The PPh4+ counterions have been replaced by Na+ cations and are located at the phosphorus site of PPh4+ cations. Furthermore, the geometry used has been taken from the one determined by X-ray crystallography. We have used the 6–31G* basis set for the ligands atoms. The nickel basis set is that determined by Wachters supplemented with f-polarization function. The sodium cations have been taken as point charges (no vacant orbital on the atom), the core electrons being described by an effective core potential. This procedure, which explicitly takes into account a repulsion potential, avoids too strong orbital polarizations towards the point charges. es_ES
