In one group, including M 2 UO 4 (M=Li, Na, K) and MUO 4 (M=Ca, Sr) there are six additional oxygen atoms. Taking calcium uranate, CaUO 4 , as an example, the six oxygen atoms are arranged as a flattened octahedron , flattened along the 3-fold symmetry axis of the octahedron which also runs through the O-U-O axis (local point group D 3d at the ...

2 + 4 HF → UF 4 + 2 H 2 O (500 °C, endothermic) UF 4 + F 2 → UF 6 (350 °C, endothermic) The resulting UF 6, a white solid, is highly reactive (by fluorination), easily sublimes (emitting a vapor that behaves as a nearly ideal gas), and is the most volatile compound of uranium known to exist. [6] One method of preparing uranium ...
The uranyl ion is always associated with other ligands. The most common arrangement is for the so-called equatorial ligands to lie in a plane perpendicular to the O–U–O line and passing through the uranium atom. With four ligands, as in [UO 2 Cl 4] 2−, the uranium has a distorted octahedral environment. In many cases more than four ...
Uranyl nitrate is a water-soluble yellow uranium salt with the formula UO 2 (NO 3) 2 · n H 2 O.The hexa-, tri-, and dihydrates are known. [3] The compound is mainly of interest because it is an intermediate in the preparation of nuclear fuels.
Sodium diuranate, also known as the yellow oxide of uranium, is an inorganic chemical compound with the chemical formula Na 2 U 2 O 7. It is a sodium salt of a diuranate anion. It forms a hexahydrate Na 2 U 2 O 7 ·6H 2 O. Sodium diuranate is commonly referred to by the initials SDU. [1] Along with ammonium diuranate it was a component in early ...
