Three
new potassium uranyl borates, K12[(UO2)19(UO4)(B2O5)2(BO3)6(BO2OH)O10] ·nH2O (TPKBUO-1), K4[(UO2)5(BO3)2O4]·H2O (TPKBUO-2), and K15[(UO2)18(BO3)7O15] (TPKBUO-3), were synthesized under high-temperature/high-pressure conditions.
In all three compounds, the U/B ratio exceeds 1. Boron exhibits BO3 coordination only, which is different from other uranyl borates
prepared at room temperature or under mild hydrothermal conditions.
A rare uranium(VI) tetraoxide core UO4O2, which
is coordinated by two BO3 groups, is observed in the structure
of TPKBUO-1. Both structures of TPKBUO-1 and TPKBUO-3 contain three different coordination environments
of uranium, namely, UO4O2, UO2O4, and UO2O5 and UO2O4, UO2O5, and UO2O6 bipyramids in TPKBUO-1 and TPKBUO-3, respectively.
