LABORATORY GAS-PHASE DETECTION OF THE CYCLOPROPENYL CATION (c-C 3 H 3 + )

K rate coefficients for the reaction of OH with i − C 3 H 7 I , n − C 3 H 7 I and C 3 H 8

The kinetics of the title reactions were investigated using the laser photolysis resonance fluorescence method, employing the sequential two-photon dissociation of NO2 in the presence of H2 as the OH source. The 298 K rate constant for OH + C3H8 was found to be (1.15 ± 0.1) × 10−12 cm s−1, in excellent agreement with the literature recommendation, and with a separate determination using HNO3 ph...

Host – guest properties of the trinuclear arene – ruthenium cluster cation [ H 3 Ru 3 ( C 6 H 6 ) ( C 6 Me 6 ) 2 ( O ) ] þ

The trinuclear arene–ruthenium cluster cation [H3Ru3(C6H6)(C6Me6)2(O)] þ, containing a l3-oxo cap and three arene ligand that span a hydrophobic pocket above the metal skeleton, has been crystallised as tetrafluoroborate salt in the presence of variou guest molecules. The host–guest complexes have been characterised by single-crystal X-ray structure analysis. With chloroform a the guest molecul...

Dinitrogen addition to c - C 5 H 5 Fe + , C 6 H 6 Fe + and FeO + in the gas phase

Results of an experimental study using the selection-ion flow tube technique are reported for reactions of bare Fe + and iron containing FeX ÷ cations (X = C6H 6 (or B), c-C5n 5 (or Cp), O, (Cp)2, B 2) with dinitrogen at 294 _+ 3 K and at a helium buffer-gas pressure of 0.35 _+ 0.01 Torr. Fe z, B2Fe + and Cp2Fe + do not react with dinitrogen. A very slow sequential addition of two N z molecules...

Strong H(2) binding and selective gas adsorption within the microporous coordination solid Mg(3)(O(2)C-C(10)H(6)-CO(2))(3).

The synthesis of Mg3(NDC)3(DEF)4 (NDC = 2,6-naphthalenedicarboxylate, DEF = N,N-diethylformamide, 1), the first porous metal-organic framework solid incorporating Mg2+ ions, is reported. Its structure consists of linear Mg3 units linked via NDC bridges to form a three-dimensional framework, featuring one-dimensional channels filled with DEF molecules. Significantly, its framework is fully analo...
