Cyclopentadienyl- and Pentamethylcyclopentadienylbis(isocyanide)cobalt(I)

Synthesis and molecular structure of (g-pentamethyl-cyclopentadienyl) (g-cyclopentadienyl) hexacarbonyl molybdenum tungsten

The metathesis reaction of Cp*(CO)3MoBr and NaW(CO)3Cp produced Cp*(CO)3Mo–W(CO)3Cp (1), featuring an unsupported Mo–W bond. Exposure of solutions of 1 to light leads to the quantitative formation of the corresponding homometallic dimers. In the solid state, the title complex exhibits an anti-arrangement of the g-cyclopentadienyl and the g-pentamethylcyclopentadienyl ligands and six terminal ca...

Solvation of cyclopentadienyl and substituted cyclopentadienyl radicals in small clusters. II. Cyanocyclopentadienyl with polar solvents

Pentaarylfullerenes as noncoordinating cyclopentadienyl anions.

The first example of an early-transition-metal complex involving a pentaarylfullerene was prepared. Instead of half-sandwich complexes, solvent separated ion pairs were obtained in which the pentaarylfullerene moiety acts as noncoordinating cyclopentadienyl anion.

Tricarbonyl(η5-cyclopentadienyl)(trifluorohydroxyborato)tungsten.

The title compound, [W(C(5)H(5))(HOBF(3))(CO)(3)], has a four-legged piano-stool geometry which is typically found for C(5)H(5)W(CO)(3)X complexes. The HOBF(3)(-) anion is the hydrolysis product of BF(4)(-) and is coordinated via oxygen.

Silyl Derivatives of the Mixed Sandwiches Cyclopentadienyl Manganese Benzene and Cyclopentadienyl Manganese Biphenyl, CpMn(C6H6) and CpMn(C6H5-Ph)

Mixed manganese sandw ich complexes containing a silyl-substituted cyclopentadienyl ring, e. g. (rj5 -C5 H4-R)Mn(7/6-C6H6) (3a c) and (775-C 5H4-R)M n(r/6-C6H5-Ph) (4a c); (R = SiM e3 (a), Si2M e_5 (b) and SiM e^'Bu (c)), were obtained in low yield via interm ediates {(r^-CsH*R)M nCl} and their reaction with phenyl G rignard reagents.
