Research Abstract

Many of the uranium complexes at their oxidation states of +5 (5f1 electron configuration), +4 (5f2 configuration), and +3 (5f3 configuration) have ligand field of Cn with an-axis symmetry. Our experimental investigation were achieved by synthesis of uranium complexes with such variety of oxidation state and electronic configuration and discussed on the ligand field states on ground state.
