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…
Evidence of C-H…O hydrogen bonds in liquid 4-ethoxybenzaldehyde from NMR and vibrational spectroscopies. Abstract Raman, FTIR, and NMR (both 13C and 17O) spectroscopies are used in a complementary way in order to study the occurrence of C−H···O intermolecular hydrogen bonds in liquid 4-ethoxybenzaldehyde (4EtOB). Additional information concerning the structure of the possible dimers is obtained…
Interactions of cationic and neutral molybdenum complexes with β-cyclodextrin host molecules. Abstract The inclusion compounds formed between β-cyclodextrin (β-CD) and the tetrafluoroborate salts [Cp‘Mo(η4-C6H8)(CO)2][BF4] and the neutral derivatives Cp‘Mo(η3-C6H7)(CO)2 [Cp‘ = Cp (η5-C5H5), Ind (η5-C9H7)] were studied by means of elemental analysis, FTIR spectroscopy, thermogravimetric analysis (TGA), powder X-ray diffraction (XRD), and magic-angle spinning (MAS)…
