TL;DR: The molecular structure determination of triscyclopentadienyltitanium shows one cyclopentadiyl ligand is bonded to the metal by only two carbons and an M.O. description in terms of a three-centre, four-electron bonding model is suggested as mentioned in this paper.

TL;DR: The carboxylato-compounds benzene Mo(π-C3H5)L, where L = O2CH, O2CMe, O 2CMe and O 2 CPh, and related derivatives are described in this article.
Abstract: The carboxylato-compounds benzene Mo(π-C3H5)L, where L = O2CH, O2CMe, O2CPh, O2CCH2[Fe(CO)2[π-(π-C5H5)], and related derivatives are described. The complexes where L = NH2CH2CO2 or NH2[CH2]2S have been prepared. The latter reacts with methyl iodide forming the cation {C6H6Mo(π-C3H5)(MeS[CH2]2NH2)}+. β-Diketone derivatives where L = MeCOCHCOMe or MeCOCHCO(OEt) have also been isolated.

TL;DR: In this paper, the preparation and properties of bis-π-allyl derivatives (C6H5R)Mo(π-C3H5)2 are described.
Abstract: The preparation and properties of the bis-π-allyl derivatives (C6H5R)Mo(π-C3H5)2 are described. The butadiene cation [C6H6Mo(π-C3H5)C4H6]+ reacts readily with nucleophiles (Nu = CN, OMe, SMe, H) to give the neutral π-allylic derivatives C6H6Mo(π-C3H5)(π-NuCH2C3H4).

TL;DR: In this article, an asymmetric structure for the latter was suggested by 1H n.m. spectra at 270 MHz and double-resonance experiments, and the cations [(C6H6R′)Mo(π-C3H5)L2′]+, (R′= H or Me, L2′= en, bipy, and o-phenylenediamine) are also described.
Abstract: The dimer [C6H6Mo(π-C3H6)Cl]2 is cleaved by chelate ligands L2 giving the cations [C6H6Mo(π-C3H5)L2]+[L2= Ph2PCH2CH2PPh2(dppe), Me2PCH2CH2PMe2(dmpe), or (MeSCH2)2]. The cations react with nucleophiles (R–= H–, Bun, and, when L2= dppe, CN–) giving the neutral cyclohexadienyl derivatives [(C6H6R)Mo(π-C3H5)L2]. An asymmetric structure for the latter is suggested by 1H n.m.r. spectra at 270 MHz and double-resonance experiments. The cations [(C6H6R′)Mo(π-C3H5)L2′]+, (R′= H or Me, L2′= en, bipy, and o-phenylenediamine) are also described.

TL;DR: In this paper, the dimeren Verbindungen (I) reagieren mit Allylmagnesiumchlorid im Uberschus in wasserfreiem THF zu den Komplexen (IIa), die im Gegensatz zu Bis-[n-allyH-nickel keine Reaktivitat gegenuber Dimethylphenylphosphin oder Athylendiamin zeigen.
