An anionic Fe(II) complex, (BMIM)4[Fe(CN)6] (where BMIM is 1-butyl-3-methylimidazolium), was synthesized in ionic liquid [BMIM][PF6] under reflux condition. The complex was characterized by elemental analysis and spectroscopic methods. The magnetite (Fe3O4) nanoparticles were prepared by the hydrothermal and solvothermal (in ionic liquid [BMIM][PF6]) methods from (BMIM)4[Fe(CN)6] as a precursor...

The photoelectron spectrum of the uracil-alanine anionic complex (UA)(-) has been recorded with 2.540 eV photons. This spectrum reveals a broad feature with a maximum between 1.6 and 2.1 eV. The vertical electron detachment energy is too large to be attributed to an (UA)(-) anionic complex in which an intact uracil anion is solvated by alanine, or vice versa. The neutral and anionic complexes o...

The effect of different kinds of surfactants in various concentrations incorporated in an inert matrix, on the release of procainamide hydrochloride, as a cationic model compound, was investigated in this study. Sodium lauryl sulfate and sodium stearate as anionic surfactants, cetyl pyridinium chloride and cetyltrimethyl ammonium bromide as cationic and span 60 and tween 80 as non-ionic surfact...

We propose a mechanism for oligonucleotide (ODN) release from cationic lipid complexes in cells that accounts for various observations on cationic lipid-nucleic acid-cell interactions. Fluorescent confocal microscopy of cells treated with rhodamine-labeled cationic liposome/ fluorescein-labeled ODN (F-ODN) complexes show the F-ODN separates from the lipid after internalization and enters the nu...

Anisotropy of anionic sites on plasma membranes has been implicated in contact phenomena at cell surfaces (16, 17). Recent evidence indicates that charge anisotropy may be important among intracellular membranes also, since distribution of anionic sites has been related to structural organization of mitochondrial membranes (8). The use of cationic ferritin has been introduced by Danon et al. (2...

Hexamethyl-phospho-ramide (hmp), tetra-thio-molybdate, silver sulfide and dysprosium nitrate were self-assembled to form an anionic [AgMoS(4)](n) (n-) chain in the title complex, {[Dy(NO(3))(2)(C(6)H(18)N(3)OP)(4)][AgMoS(4)]}(n). The central Dy atom in the cation is coordinated by eight O atoms from two nitrate and four hmp ligands, resulting in a distorted square-anti-prismatic environment. To...

1. (10 pts) The term migratory insertion is often used to describe the general process of a neutral metal bound ligand reacting with a cisoidal anionic ligand to produce a new coupled anionic ligand. For example, the reaction of 3a,b(mono) to produce 4a,b. There are separate, more specific descriptions for this general process called migration and insertion. An insertion specifically refers to ...
