TLDR
A new thallium(I) uranate (VI) of composition Tl4UO5 was isolated and characterised by X-ray, i. r. and chemical analyses as discussed by the authors.Abstract:
A new thallium(I) uranate(VI) of composition Tl4UO5 was isolated and characterised by X-ray, i. r. and chemical analyses. The compound dissociated into thallium(I) oxide and Tl2UO4 on heating to 230°C and its subsequent thermal behaviour depended on the volatilisation and oxidation characteristics of the thallium(I) oxide released.
Darstellung und Charakterisierung eines neuen Thallium(I)- uranates, Tl4UO5
Ein neues Thallium(I)-uranat(VI), Tl4UO5, wurde dargestellt und durch Rontgen-, IR- und chemische Analyse charakterisiert. Beim Erhitzen auf 230°C dissoziiert die Verbindung in Tl2O und Tl2UO4, und das weitere thermische Verhalten ist gekennzeichnet von der Fluchtigkeit und Oxydationscharakteristik des freigesetzten Tl2O.read more

Four thallium(I) uranates(VI), their preparation, structure and properties
TL;DR: In this paper, four thallium(I) uranates (VI), Tl4UO5,T l 2UO4,Tl 2U2O7 and Tl2U3O10, were prepared and their IR, and, for the first time, their Raman, electronic and X-ray absorption (EXAFS) spectra have been measured.
