Stabilization of dioxochromium(VI) in the complex with tetra[benzo]porphyrazine and two oxo ligands: DFT quantum-chemical consideration

Abstract

Based on the results of a quantum chemical consideration in the framework of DFT OPBE/TZVP and B3PW91/TZVP methods, the possibility of the self-existence of a chromium heteroligand complex with (NNNN)-donor macrocyclic ligand – tetra[benzo]porphyrazine and two oxo ligands where chromium oxidation degree is (+6), have been shown. The data on the key structural parameters and also, on multiplicity of the ground state of the given macrocyclic metal complex have also been presented.
