A mixed-valent Cr<sup>I</sup>–Cr<sup>II</sup> binuclear complex, {κ<sup>1</sup>,κ<sup>2</sup>,κ<sup>3</sup>-<i>N</i>,<i>P</i>,<i>P</i>-cyclo[(Ph)PCH<sub>2</sub>N(CH<sub>2</sub>Ph)CH<sub>2</sub>]}<sub>2</sub>(CrCl<sub>2</sub>)[Cr(μ-Cl)(AlClMe<sub>2</sub>)]·4toluene (<b>1</b>), of a P<sub>2</sub>N<sub>2</sub> cyclic ligand was obtained upon treatment of the chromium precursor with alkylaluminum. Complex <b>1</b> was accessible from either its trivalent or divalent precursors, and density functional theory calculations revealed the presence of only σ- and π-orbital interactions in the Cr–Cr bond
