Abstract
The reactions of trivalent lanthanides and actinides with molten boric acid in high chloride concentrations result in the formation of M4[B 16O26(OH)4(H2O)3Cl 4] (M=Sm, Eu, Gd, Pu, Am, Cm, Cf). This cubic structure type is remarkably complex and displays both chirality and polarity. The polymeric borate network forms helical features that are linked via two different types of nine-coordinate f-element environments. The f-f transitions are unusually intense and result in dark coloration of these compounds with actinides.
