Understanding of the structural chemistry in the uranium oxo-tellurium system under HT/HP conditions.

ABSTRACT: The study of phase formation in the U-Te-O systems with mono and divalent cations under high-temperature high-pressure (HT/HP) conditions has resulted in four new inorganic compounds: K₂ [(UO₂) (Te₂O₇)], Mg [(UO₂) (TeO₃)₂], Sr [(UO₂) (TeO₃)₂] and Sr [(UO₂) (TeO₅)]. Tellurium occurs as Te^IV, Te^V, and Te^VI in these phases which demonstrate the high chemical flexibility of the system. Uranium VI) adopts a variety of coordinations, namely, UO₆ in K₂ [(UO₂) (Te₂O₇), UO₇ in Mg [(UO₂) (TeO₃)₂] and Sr [(UO₂) (TeO₃)
