Electronic structure of UO2Cl42-, NpO2Cl42- and PuO2Cl42-

Calculations of electronic structure of UO2Cl42-, NpO2xCl42- and PuO2Cl42- anions by quasirelativistic Xα-method of scattered waves are made. Electron and X-ray electron spectra of the compounds have been interpreted. It is shown that in AnO2Cl42--compounds covalent constituent of An-O chemical bond increases as compared with AnO22+ isolated cation at the expense of electron density transfer from Cl ions to valency orbitals of An
