Cluster phase chemistry: gas-phase reactions of anionic sodium salts of dicarboxylic acid clusters with water molecules.

Chapter 4. Cluster Phase Chemistry: Gas Phase Reactions of Anionic Sodium Salts of Dicarboxylic Acid Clusters with Water Molecules

Cluster phase chemistry: collisions of vibrationally excited cationic dicarboxylic acid clusters with water molecules initiate dissociation of cluster components.

A homologous series of cationic gas-phase clusters of dicarboxylic acids (oxalic acid, malonic acid, succinic acid, glutaric acid, and adipic acid) generated via electrospray ionization (ESI) are investigated using collision-induced dissociation (CID). Singly charged cationic clusters with the composition (Na(+))(2n+1)(dicarboxylate(2-))(n), where n = 1-5, are observed as major gas-phase specie...

X-Ray, Crystal Structure and Solution Phase Studies of a Polymeric SrII Compound

In the crystal structure of the title polymeric compound, [C42H38N6O33Sr5.2(H2O)]n, five independent metal atoms (Sr1-Sr5) have different coordination environments. The Sr1 and Sr5 atoms are nine coordinated and feature distorted tricapped trigonal-prismatic and capped square-antiprismatic geometries, respectively....

Synthesis and crystal structure compound Adeninium Bis(pyridine-2,6-dicarboxylate) Chromate(III) pyridine-2,6-dicarboxylic acid tetra hydrate

A new supramolecular compound of adeninium bis(pyridine-2,6-dicarboxylate) Chromate(III) pyridine-2,6-dicarboxylic acid tetrahydrate (AdH+)[Cr(pydc)2](H2pydc).4H2O (1) (where Ad and H2pydc are adenine and pyridine-2,6-dicarboxylic acid, respectively) was synthesized via proton transfer method and its structure was determined using single crystal X-ray diffraction technique. This compound crysta...

Ambient preparation and reactions of gas phase silver cluster cations and anions.

Electrospray ionization of metal salt solutions followed by ambient heating transforms the resulting salt clusters into new species, primarily naked ionic metal clusters. The experiment is done by passing the clusters through a heated coiled loop outside the mass spectrometer which releases the counter-anion while generating the anionic or cationic naked metal cluster. The nature of the anion i...
