Four-component relativistic calculations were performed on the mono-aqua and mono-ammine complexes of trivalent actinoid (An=Ac,Cm,Lr) and lanthanoid (Ln=La,Gd,Lu) ions. Metal-ligand distance, stabilization energy, and Mulliken population were evaluated in a systematic manner. Difference between water and ammonia as the ligands was addressed.
