Encapsulation of cyano(cyclopentadienyl) complexes of iron with b-cyclodextrin. Abstract Inclusion compounds have been prepared comprising g -cyclodextrin (CD) molecules as the host and half-sandwich cyano complexes of iron as the guests. High yields of crystalline one-to-one adducts were obtained by treatment of CpFe(CO) 2 CN and K[CpFe(CO)(CN) 2 ] with g -CD. In the case…

C-H···O Bonded Dimers in 2-Methoxy-Benzaldehyde Studied by X-ray Crystallography, Vibrational Spectroscopy, and Ab initio Calculations. Abstract The crystal structure of 2-methoxy-benzaldehyde reveals the presence of several intra- and intermolecular C–H⋯O short contacts, the strongest one forming a dimer linked by the CO and C(3)–H groups of adjacent molecules. In the liquid state, the occurrence of…

The effect of trimethylsilyl substituents on the ring-slippage of bis-indenyl-molybdenocene derivatives. Abstract A group of new trimethylsilyl indenyl derivatives of molybdenum is reported, starting from the allyl compound TMSIndMo(η3-C3H5)(CO)2 [TMSInd=η3-SiMe3C9H6]. The novel allyl Mo(II) complex, which is synthesized by the reaction of Mo(η3-C3H5)(CO)2(NCMe)2Cl with Li(TMSInd) in THF, is the precursor to trimethylsilyl indenyl derivatives. Treatment…

Synthesis and Characterization of two Novel Large-pore Crystalline Vanadosilicates. Abstract Two novel large-pore sodium vanadosilicates (Aveiro-Manchester, structure numbers 13 and 14) containing stoichiometric amounts of vanadium (Si/V = 10 and 4, respectively) have been synthesized. Only one other example of a large-pore vanadosilicate (AM-6) is known. AM-13 and AM-14 were characterized by bulk chemical analysis…

Experimental and theoretical studyof the interaction of molybdenocene dichloride (Cp2MoCl2) with β-cyclodextrin. Abstract A crystalline 1:1 inclusion complex was isolated from the reaction of β-cyclodextrin (β-CD) with aqueous Cp2MoCl2. The existence of a true inclusion complex in the solid-state was confirmed by a combination of powder X-ray diffraction (XRD), thermogravimetric analysis (TGA), FTIR and Raman…
