摘要

Analysis of the topology and delocalization of the electron density with the quantum theory of atoms in molecules (QTAIM) shows that the Cr-2 dimer when supported by two diazadiene ligands has a degree of bonding of 3.6-slightly less than that of a formal quadruple bond. The metal-ligand complex is held together by relatively weak dative bonds. Out-of-plane lone-pair-like charge concentrations on the nitrogen atoms are oriented so as to maximally avoid areas of charge concentration in the distorted inner-valence shell of the chromium atoms.
