RT can be used to synthesize actinide complexes. RT has been used to synthesize uranium halides using uranium metal and mercury halides as shown:
:U + HgX → UX + Hg (X = Cl, Br, I)
This actinide RT reaction can be done with multiple mercury compounds to coordinate ligands other than halogens to the metal: 
:2 U + 3 (CH)Hg + HgCl → 2 (CH)UCl + 4 Hg
