Four new ethylenediamine-templated iron arsenates and fluoroarsenates have been hydrothermally synthesized from iron metal, hydrofluoric and arsenic acids, and ethylenediamine. Fe(H2AsO4)(HAsO4)2.enH2.H2O (1) is one-dimensional and contains chains, FeIIIFeIIF2(HAsO4)(AsO4).enH2.2H2O (2) is a layered fluoroarsenate, and Fe3(HAsO4)6.enH2.NH3.NH4 (3) and Fe2F2(AsO4)2(H2O).enH2 (4) are an arsenate ...

AIM The present study was designed to investigate the effects of estradiol-ethylenediamine derivative on perfusion pressure and coronary resistance in rats. An additional aim was to identify the molecular mechanisms involved. METHODS The Langendorff model was used to measure perfusion pressure and coronary resistance changes in isolated rat heart after estradiol-ethylenediamine derivative alo...

Knowledge of hydrogen bonds is important in a wide range of scientific fields. However, information on the electronic state of hydrogen bonded molecules in liquids and solutions is still limited. We applied X-ray emission and absorption spectroscopy to observe the electronic state around oxygen of water and investigate the solvent dependence of occupied and unoccupied valence electronic states ...

Hollow CdS nanoboxes, having paper-thin walls of well-defined facets, were synthesized at 170 degrees C via a simple reaction using Na(2)SeO(3) for interior quasitemplates and ethylenediamine for exterior molecular templates.

We describe the synthesis of N -functionalised phosphinecarboxamides obtained by reaction 2-phosphaethynolate anion (PCO ? ) with diamines, specifically hydrazine, methylenediamine and ethylenediamine.

At present ethylenediamine is one of the more studied nitrogen— —ligands. The main physico—chemical properties of this diamine are reported in this survey. The fundamental techniques for its purification and storage and its acid—base characteristics in aqueous solution are described. The formation constants of the complexes with various metal ion, the thermodyna mic values relative to the react...

A novel, mixed-valent copper(I)-copper(II) complex, {[bis(ethylene-diamine)copper(II)] bis[diiodocuprate(I)]} (1), has been prepared by electrochemical dissolution of a sacrificial copper anode in a solution of ethylenediamine (en), I2 and tetraethylammoniumperchlorate (TEAP) as supporting electrolyte in acetonitrile (AcN)and characterized by single-crystal X-ray structure determination. The cr...

We have previously demonstrated that metal oxide ultrathin films, by themselves, can produce imprinted cavities for organic molecules. In the present study, memorization of the coordination environments of metal ions was achieved by incorporation of diamine chelating ligands in thin films of metal oxides. The films imprinted with Cu2+ or Zn2 + showed selective binding to the template over the c...
