The solvent adducts of the tetravalent actinoid chlorides ThCl 4 and UCl 4 have been isolated with methanol as [ThCl 4 (MeOH) 4 ] 1 and [UCl 4 (MeOH) 4 ] 2 , and with ethanol as [ThCl 4 (EtOH) 4 ] 3 and [UCl 4 (EtOH) 4 ] 4 . In hydrochloric acid [ThCl 2 (H 2 O) 7 ](Cl) 2 (H 2 O) 2 5 forms, which is isotypic to the known [UCl 2 (H 2 O) 7 ](Cl) 2 (H 2 O) 2 6 . The adducts have been analysed using SXRD, IR, CHN, TGA‐MS and PXRD. The material can be isolated from saturated organic ( 1 – 4 ) or acidic aqueous ( 5 – 6 ) solutions, however, drying of the isolated material results in loss of HCl and the formation of oxide species, confirmed by the isolation of U 3 O 8 after complete thermal decomposition.
