General Description

Uranium, chlorotris(h5-2,4-cyclopentadien-1-yl)- is a complex chemical compound containing uranium and chlorotris(h5-2,4-cyclopentadien-1-yl) ligands. Uranium, chlorotris(h5-2,4-cyclopentadien-1-yl)- is often used in organometallic chemistry and as a precursor for the synthesis of various uranium-based compounds. It is known for its high reactivity and is often employed in the production of uranium-containing materials for use in nuclear fuel and other industrial applications. However, due to the radioactive nature of uranium, strict safety protocols must be followed when handling this compound to minimize the risk of radiation exposure.

ZUR KENNTNIS DES DIAQUA-TRIS(η5-CYCLOPENTADIENYL)URAN(IV)KATIONS: ISOLIERUNG UND EIGENSCHAFTEN DES SALZES NO3

In contrast to the re-examined system which appears to contain weakly hydrogen-bonded H2O rather than a genuine + cation, the salt-like precipitate NO3 is shown to be the first well-defined +-derivative of adequate stability, the anion of which is not coordinated to the central metal.Ample evidence for the existense of similar, but mostly metastable precipitation products X and , respectively, (X = e.g.Cl, Br, I, ClO4, HCO2 including the replacement of H2O by NH3) is presented.Some interesting, common features of organo-uranium- and -tin-systems, R3MIVX, are elucidated.

Oxidative addition of organic halides to (ν-C5H5)3U(THF) (THF = tetrahydrofuran). A convenient new synthesis of triscyclopentadienyl uranium(IV) hydrocarbyl complexes

Cp3U(THF) (Cp = η-C5H5; THF = tetrahydrofuran) react with organic halides RX to give the equimolecular mixture of the Cp3UX and Cp3UR compounds.The features of the reaction are characteristic of an atom abstraction oxidative addition mechanism.Treatment o

Molecular structure and charge distribution in organometallics of the 4f and 5f elements. I. Dipole moment and charge distribution of the actinoid(IV) tetracyclopentadienides, An(C5H5)4

The dipole moments of the tetracyclopentadienides, An(C5H5)4, of the lighter actinoids thorium, uranium and neptunium were measured in benzene solution. Although the compounds in the solid state have a quasi-Td molecular symmetry their dipole moments are not zero, owing to lowering of the molecular symmetry. The origin of the nonzero dipole moments is discussed.

Bi- and triheteronuclear complexes of uranium and group VI transition metals

The new heterobimetallic compounds Cp3U[OCM(CO)2Cp′] containing uranium and group VI transition metals are synthesized from Cp3UCl and Na[M(CO)3Cp′] or from Cp3UCH3 and H[M(CO)3Cp′] (M = Mo, W; Cp = C5H5; Cp′ = C5H5 or C5Me5). In a same manner, the trimetallic Cp2U[OCMo(CO) 2Cp]2 is obtained starting from Cp2U(NEt2)2 and H[Mo(CO)3Cp]. All these complexes exhibit low CO stretching frequencies characteristic of isocarbonyl linkages between uranium and Mo or W atoms.
