The phoszone ligand [(Ph2P)(bis-3,5-CF3-Ph)]NN=CH(penta-fluoro-Ph) transformed in liquid CO2 at room temperature in presence of [Rh(cod)2]OTf into [Rh(cod)(η2-P,P′-Ph2POPPh2)]OTf. Replacing the O-atom in Ph2POPPh2 by a PrN-group leads to the ligan

The absorption spectrum of tris[hydrotris(1-pyrazolyl)borato]uranium(III) (UTp3) was run at room and low temperatures. From the spectra obtained, a truncated crystal field (CF) splitting pattern could be derived, and simulated by fitting the free par

Oxidation of (C 5 H 5 ) 3 U III ·THF with oxygen in tetrahydrofuran yields the linear bridged complex [(C 5 H 5 ) 3 U][μ-O]. Three cyclopentadienyl rings are η 5 -covalently bonded to each uranium atom to form a distorted tetrahedron with one brid

The title compound 1 is the complex of a novel ligand. It is formed from [(CH3C5H4)Mn(CO)2·thf] and (CH3)3C-C=P, presumably with uptake of H2O. The bis(phosphavinyl) ether in 1 functions as an 8-electron donor toward the four (CH3C5H4)Mn(CO)2 units
