We have synthesized and studied thermographically some hydrates of trichromatodiuranylates (NH/sub 4/)/sub 2/(UO/sub 2/)/sub 2/(CrO/sub 4/)/sub 3//centered dot/5H/sub 2/O and R/sub 2/(UO/sub 2/)/sub 2/(CrO/sub 4/)/sub 3//centered dot/6H/sub 2/O (R=K, Rb). We present the crystallographic characteristics of the compounds and discuss hypotheses concerning their structure. X-ray phase, x-ray diffraction, differential thermal, thermogravimetric, and chemical analyses were conducted.
