Periodic trends in trivalent actinide halides, phosphates, and arsenates

“…16 Uranium hexafluoride [17][18][19][20][21][22][23][24][25][26] and plutonium hexafluoride [27][28][29][30][31] probably are the most studied actinide halides due to their importance in the enrichment of fission material for nuclear applications. [32][33][34] Few reports on actinide phosphates and arsenates, mainly focussing on uranium compounds [35][36][37][38][39] and/ or pre-uranium compounds [40][41][42][43][44][45][46] are available in the literature. In this study we are focussing on the +3-oxidation state of the actinide elements as it is the common oxidation state for all of them.…”

“…3,7 Studies have reported thorium phosphates and arsenates, however not in 1 : 1 neutral form where thorium would occur as Th(III). [40][41][42][44][45][46] As thorium is very stable in the +4 oxidation state (stable noble gas configuration), it is highly unlikely for thorium to exhibit a stable +3 state in the ground state at room temperature. This also agrees with the literature.…”
