Impact of Ligand Structures on Precipitation Reactions of Uranyl Nitrate Coordination Polymers with Diamide/Dicarbamide Cross-Linkers.

ABSTRACT: In relevance to advanced nuclear fuel recycling, we investigated the structural chemistry of UO₂(NO₃)₂ coordination polymers bearing trans-1,4-cyclohexanediamine-based cyclic/acyclic diamides/dicarbamide cross-linkers (L1-L6) to know how the ligand structure impacts precipitation behavior of UO₂ ²⁺ from HNO₃(aq). In a similar manner to the γ-lactam analogue (L2) we reported previously, 1D coordination polymers of [UO₂(NO₃)₂(Lx)] _n were obtained in the use of any Lx's having β-/δ-lactam (L1, L3), acetamide (L4), propionamide (L5), and N,N,N'-trimethylcarbamide (L6) terminals. These compounds exhibit the typical structural features of
