Thorium(IV) molecular clusters with a hexanuclear Th core.
Karah E. Knope,Richard E. Wilson,Monica Vasiliu,David A. Dixon,David A. Dixon,Lynda Soderholm +5 more
TL;DR: Three polynuclear thorium(IV) molecular complexes have been synthesized under ambient conditions from reactions of an amorphous Th precipitate, obtained via hydrolysis, with carboxylate functionalized ligands using R-COO(-) ligands to form discrete, neutral molecular clusters.

Uranyl sensitization of samarium (III) luminescence in a two-dimensional coordination polymer
Karah E. Knope,Daniel T. de Lill,Clare E. Rowland,Paula M. Cantos,Ana de Bettencourt-Dias,Christopher L. Cahill +5 more
TL;DR: The synthesis, crystal structure, and luminescent behavior of 1, as well as those of the isostructural terbium, erBium, and ytterbium analogues are reported.
Journal ArticleDOI
Structural variation within homometallic uranium(VI) carboxyphosphonates: in situ ligand synthesis, directed assembly, metal-ligand coordination and hydrogen bonding.
TL;DR: Four 2D uranium(VI) carboxyphosphonates, (UO 2)(O 3PCH 2CO 2H) ( 1, 2, and 3) have been prepared using hydrothermal techniques and their crystal structures have been determined by single-crystal X-ray diffraction, and structural features have been confirmed by infrared spectroscopy.
Journal ArticleDOI

Kate L. Ziegelgruber,Kate L. Ziegelgruber,Karah E. Knope,Mark Frisch,Christopher L. Cahill,Christopher L. Cahill +5 more
TL;DR: A thorium (IV) coordination polymer, Th(C5H2N2O4)2(H2O)2 (1), has been prepared under the hydrothermal reaction of thorium nitrate tetrahydrate and 3,5-pyrazinedicarboxylic acid (H3pdc) as discussed by the authors.
