Abstract
A mixed-valent Cr-I-Cr-II binuclear complex, {kappa(1),kappa(2),kappa(3)-N,P,P-cyclo[(Ph)PCH2N(CH2Ph)CH2]}(2)(CrCl2)[Cr(mu-Cl)(AlClMe2)].4toluene (1), of a P2N2 cyclic ligand was obtained upon treatment of the chromium precursor with alkylaluminum. Complex 1 was accessible from either its trivalent or divalent precursors, and density functional theory calculations revealed the presence of only s- and p-orbital interactions in the Cr-Cr bond.
