In this report, using the ab initio method of stability and electron-orbital properties of the complex (۲,۶۶-diaminopyridinium bis (۴-hydroxy-pyridine-۲, ۶-dicarboxylate) dihydrate chromate III) with a change of ligand at position ۱۷ It has been studied with ligands such as F, Cl, Br,,, and. The results indicate changes in energy levels, bipolar moments, and sustainability rates due to these changes in these bonds.
