(NH₄)₂[UO₂Cl₄]·2H₂O, a new uranyl tetra-chloride with ammonium charge-balancing cations.

ABSTRACT: A new uranyl tetra-chloride salt with chemical formula, (NH₄)₂[UO₂Cl₄]·2H₂O, namely, di-ammonium uranyl tetra-chloride dihydrate, 1, was prepared and crystallized via slow evaporation from a solution of 2 M hydro-chloric acid. As confirmed by powder X-ray diffraction, the title compound crystallizes with an ammonium chloride impurity that formed as a result of the breakdown of a triazine precursor. The (UO₂Cl₄)^2- dianion is charge balanced by ammonium cations, while an extensive hydrogen-bond network donated from structural water mol-ecules stabilize the overall assembly. Compound 1 adds to the extensive collection of actinyl tetra-chloride salts, but it represents the first
